43483964 divided by 631 
We want to divide 43483964 by 631.

Advancing to step 1:
The number 631 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 631

Advancing to step 2:
631 can be fit into 43 0 times, resulting in a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Include the next digit (4) from the dividend after 43, then repeat: 434 / 631

Step 3:
When dividing 434 by 631, we get 0 with a remainder of 434.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 434, we get 434.
Fetch the next digit (8) from the dividend, attach it to 434 and continue: 4348 / 631

Advancing to step 4:
631 goes into 4348 6 times with a remainder of 562.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 562 after subtracting 3786 from 4348.
Take the next digit (3) from the dividend and append it to 562, then repeat: 5623 / 631

On to step 5:
5623 divided by 631 is 8 with a remainder of 575.
Use 8 as the next digit of our solution. 
Result so far: 68.0
The remainder is 575 after subtracting 5048 from 5623.
Grab the next digit (9) from the dividend, add it to 575, then carry on: 5759 / 631

Step 6:
The number 631 fits into 5759 9 times, leaving a remainder of 80.
Put 9 as the next digit of the answer. 
Result so far: 689.0
The remainder is 80 after subtracting 5679 from 5759.
Grab the next digit (6) from the dividend, add it to 80, then carry on: 806 / 631

Advancing to step 7:
631 goes into 806 1 times with a remainder of 175.
The number 1 becomes the next digit in our result. 
Result so far: 6891.0
Subtract 631 from 806 to get 175.
Include the next digit (4) from the dividend after 175, then repeat: 1754 / 631

Let's proceed to step 8:
If we divide 1754 by 631, we get 2 and a remainder of 492.
Write down 2 as next digit of the result. 
Result so far: 68912.0
If we subtract 1262 from 1754, we get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

On to step 9:
631 can be fit into 4920 7 times, resulting in a remainder of 503.
Put 7 as the next digit of the answer. 
Result so far: 68912.7
If we take 4417 away from 4920, we end up with 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

On to step 10:
631 goes into 5030 7 times with a remainder of 613.
Record the quotient 7 as the next digit in the result. 
Result so far: 68912.77
If we take 4417 away from 5030, we end up with 613.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6130, and continue the process.

After the division, we end up with 68912.77 and a remainder of 0.613.
