Let's divide 90031586 by 630
We want to divide 90031586 by 630.

Moving on to step 1:
If we divide 9 by 630, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 630

Moving on to step 2:
630 goes into 90 0 times with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Append the next digit (0) from the dividend to 90 and continue with: 900 / 630

Advancing to step 3:
When dividing 900 by 630, we get 1 with a remainder of 270.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 270 after subtracting 630 from 900.
Fetch the next digit (3) from the dividend, attach it to 270 and continue: 2703 / 630

Let's proceed to step 4:
2703 divided by 630 is 4 with a remainder of 183.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 2520 from 2703 and we're left with 183.
Take the next digit (1) from the dividend and append it to 183, then repeat: 1831 / 630

Step 5:
The number 630 fits into 1831 2 times, leaving a remainder of 571.
Record the quotient 2 as the next digit in the result. 
Result so far: 142.0
If we subtract 1260 from 1831, we get 571.
Append the next digit (5) from the dividend to 571 and continue with: 5715 / 630

Let's proceed to step 6:
630 goes into 5715 9 times with a remainder of 45.
Use 9 as the next digit of our solution. 
Result so far: 1429.0
The remainder is 45 after subtracting 5670 from 5715.
Bring next digit (8) of the dividend behind the 45 and repeat the process: 458 / 630

Let's proceed to step 7:
630 can be fit into 458 0 times, resulting in a remainder of 458.
The number 0 becomes the next digit in our result. 
Result so far: 14290.0
Subtract 0 from 458 to get 458.
Fetch the next digit (6) from the dividend, attach it to 458 and continue: 4586 / 630

Step 8:
4586 divided by 630 is 7 with a remainder of 176.
The number 7 becomes the next digit in our result. 
Result so far: 142907.0
If we subtract 4410 from 4586, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 9:
The number 630 fits into 1760 2 times, leaving a remainder of 500.
Record the quotient 2 as the next digit in the result. 
Result so far: 142907.2
Subtracting 1260 from 1760 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Moving on to step 10:
If we divide 5000 by 630, we get 7 and a remainder of 590.
The next digit of our result is 7. 
Result so far: 142907.27
If we subtract 4410 from 5000, we get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Going ahead to step 11:
The number 630 fits into 5900 9 times, leaving a remainder of 230.
Write down 9 as next digit of the result. 
Result so far: 142907.279
If we take 5670 away from 5900, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 12:
630 can be fit into 2300 3 times, resulting in a remainder of 410.
Put 3 as the next digit of the answer. 
Result so far: 142907.2793
Subtract 1890 from 2300 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Moving on to step 13:
630 can be fit into 4100 6 times, resulting in a remainder of 320.
Record the quotient 6 as the next digit in the result. 
Result so far: 142907.27936
Subtracting 3780 from 4100 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 14:
The number 630 fits into 3200 5 times, leaving a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 142907.279365
If we subtract 3150 from 3200, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 15:
630 goes into 500 0 times with a remainder of 500.
Put 0 as the next digit of the answer. 
Result so far: 142907.279365
If we subtract 0 from 500, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 16:
If we divide 5000 by 630, we get 7 and a remainder of 590.
Use 7 as the next digit of our solution. 
Result so far: 142907.27936507
Subtracting 4410 from 5000 leaves us with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

In conclusion, the division gives 142907.27936507 with a balance of 5.9e-07.
