Let's divide 66497147 by 631
Let's see how many times 631 fits into 66497147.

Going ahead to step 1:
The number 631 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 631

On to step 2:
The number 631 fits into 66 0 times, leaving a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Append the next digit (4) from the dividend to 66 and continue with: 664 / 631

Advancing to step 3:
The number 631 fits into 664 1 times, leaving a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 631 from 664, we get 33.
Append the next digit (9) from the dividend to 33 and continue with: 339 / 631

Advancing to step 4:
When dividing 339 by 631, we get 0 with a remainder of 339.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 339, we end up with 339.
Fetch the next digit (7) from the dividend, attach it to 339 and continue: 3397 / 631

Step 5:
631 can be fit into 3397 5 times, resulting in a remainder of 242.
Use 5 as the next digit of our solution. 
Result so far: 105.0
Subtract 3155 from 3397 to get 242.
Append the next digit (1) from the dividend to 242 and continue with: 2421 / 631

Going ahead to step 6:
If we divide 2421 by 631, we get 3 and a remainder of 528.
Use 3 as the next digit of our solution. 
Result so far: 1053.0
If we take 1893 away from 2421, we end up with 528.
Bring next digit (4) of the dividend behind the 528 and repeat the process: 5284 / 631

Step 7:
When dividing 5284 by 631, we get 8 with a remainder of 236.
The number 8 becomes the next digit in our result. 
Result so far: 10538.0
If we take 5048 away from 5284, we end up with 236.
Grab the next digit (7) from the dividend, add it to 236, then carry on: 2367 / 631

Step 8:
If we divide 2367 by 631, we get 3 and a remainder of 474.
Use 3 as the next digit of our solution. 
Result so far: 105383.0
Subtracting 1893 from 2367 leaves us with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Let's proceed to step 9:
631 goes into 4740 7 times with a remainder of 323.
Put 7 as the next digit of the answer. 
Result so far: 105383.7
Subtracting 4417 from 4740 leaves us with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Advancing to step 10:
When dividing 3230 by 631, we get 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 105383.75
Subtract 3155 from 3230 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 11:
If we divide 750 by 631, we get 1 and a remainder of 119.
Use 1 as the next digit of our solution. 
Result so far: 105383.751
If we take 631 away from 750, we end up with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Advancing to step 12:
631 goes into 1190 1 times with a remainder of 559.
Record the quotient 1 as the next digit in the result. 
Result so far: 105383.7511
If we take 631 away from 1190, we end up with 559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

The final result is 105383.7511 with a remainder of 0.00559.
