We're dividing 91434083 by 631 
Our goal is to divide 91434083 by 631.

Going ahead to step 1:
The number 631 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 631

Advancing to step 2:
If we divide 91 by 631, we get 0 and a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Grab the next digit (4) from the dividend, add it to 91, then carry on: 914 / 631

Going ahead to step 3:
If we divide 914 by 631, we get 1 and a remainder of 283.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 631 away from 914, we end up with 283.
Take the next digit (3) from the dividend and append it to 283, then repeat: 2833 / 631

Step 4:
631 can be fit into 2833 4 times, resulting in a remainder of 309.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 309 after subtracting 2524 from 2833.
Include the next digit (4) from the dividend after 309, then repeat: 3094 / 631

Let's proceed to step 5:
The number 631 fits into 3094 4 times, leaving a remainder of 570.
The next digit of our result is 4. 
Result so far: 144.0
Deduct 2524 from 3094 and we're left with 570.
Take the next digit (0) from the dividend and append it to 570, then repeat: 5700 / 631

On to step 6:
If we divide 5700 by 631, we get 9 and a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 1449.0
The remainder is 21 after subtracting 5679 from 5700.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 631

Step 7:
When dividing 218 by 631, we get 0 with a remainder of 218.
Record the quotient 0 as the next digit in the result. 
Result so far: 14490.0
If we take 0 away from 218, we end up with 218.
Grab the next digit (3) from the dividend, add it to 218, then carry on: 2183 / 631

Going ahead to step 8:
If we divide 2183 by 631, we get 3 and a remainder of 290.
Use 3 as the next digit of our solution. 
Result so far: 144903.0
If we take 1893 away from 2183, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 9:
631 can be fit into 2900 4 times, resulting in a remainder of 376.
The number 4 becomes the next digit in our result. 
Result so far: 144903.4
Subtract 2524 from 2900 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Let's proceed to step 10:
3760 divided by 631 is 5 with a remainder of 605.
Put 5 as the next digit of the answer. 
Result so far: 144903.45
If we take 3155 away from 3760, we end up with 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Advancing to step 11:
If we divide 6050 by 631, we get 9 and a remainder of 371.
Use 9 as the next digit of our solution. 
Result so far: 144903.459
Subtract 5679 from 6050 to get 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Going ahead to step 12:
When dividing 3710 by 631, we get 5 with a remainder of 555.
Record the quotient 5 as the next digit in the result. 
Result so far: 144903.4595
If we take 3155 away from 3710, we end up with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

On to step 13:
When dividing 5550 by 631, we get 8 with a remainder of 502.
Use 8 as the next digit of our solution. 
Result so far: 144903.45958
Subtract 5048 from 5550 to get 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Advancing to step 14:
631 can be fit into 5020 7 times, resulting in a remainder of 603.
The number 7 becomes the next digit in our result. 
Result so far: 144903.459587
Subtract 4417 from 5020 to get 603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6030, and continue the process.

Let's proceed to step 15:
The number 631 fits into 6030 9 times, leaving a remainder of 351.
Put 9 as the next digit of the answer. 
Result so far: 144903.4595879
If we subtract 5679 from 6030, we get 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Going ahead to step 16:
631 can be fit into 3510 5 times, resulting in a remainder of 355.
Record the quotient 5 as the next digit in the result. 
Result so far: 144903.45958795
The remainder is 355 after subtracting 3155 from 3510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

In conclusion, the division gives 144903.45958795 with a balance of 3.55e-07.
