45253964 ÷ 931 
We want to figure out the number of times 45253964 can be divided by 931.

On to step 1:
4 divided by 931 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 931

Moving on to step 2:
If we divide 45 by 931, we get 0 and a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Include the next digit (2) from the dividend after 45, then repeat: 452 / 931

Advancing to step 3:
The number 931 fits into 452 0 times, leaving a remainder of 452.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 452, we end up with 452.
Fetch the next digit (5) from the dividend, attach it to 452 and continue: 4525 / 931

On to step 4:
931 goes into 4525 4 times with a remainder of 801.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 3724 from 4525 and we're left with 801.
Take the next digit (3) from the dividend and append it to 801, then repeat: 8013 / 931

Moving on to step 5:
931 can be fit into 8013 8 times, resulting in a remainder of 565.
Put 8 as the next digit of the answer. 
Result so far: 48.0
The remainder is 565 after subtracting 7448 from 8013.
Include the next digit (9) from the dividend after 565, then repeat: 5659 / 931

On to step 6:
The number 931 fits into 5659 6 times, leaving a remainder of 73.
The number 6 becomes the next digit in our result. 
Result so far: 486.0
The remainder is 73 after subtracting 5586 from 5659.
Append the next digit (6) from the dividend to 73 and continue with: 736 / 931

Advancing to step 7:
The number 931 fits into 736 0 times, leaving a remainder of 736.
The next digit of our result is 0. 
Result so far: 4860.0
If we take 0 away from 736, we end up with 736.
Grab the next digit (4) from the dividend, add it to 736, then carry on: 7364 / 931

Moving on to step 8:
931 can be fit into 7364 7 times, resulting in a remainder of 847.
The next digit of our result is 7. 
Result so far: 48607.0
If we take 6517 away from 7364, we end up with 847.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8470, and continue the process.

On to step 9:
8470 divided by 931 is 9 with a remainder of 91.
The number 9 becomes the next digit in our result. 
Result so far: 48607.9
Subtracting 8379 from 8470 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 10:
931 goes into 910 0 times with a remainder of 910.
The next digit of our result is 0. 
Result so far: 48607.9
Subtracting 0 from 910 leaves us with 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9100, and continue the process.

On to step 11:
931 can be fit into 9100 9 times, resulting in a remainder of 721.
Record the quotient 9 as the next digit in the result. 
Result so far: 48607.909
Subtracting 8379 from 9100 leaves us with 721.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7210, and continue the process.

Advancing to step 12:
931 can be fit into 7210 7 times, resulting in a remainder of 693.
The number 7 becomes the next digit in our result. 
Result so far: 48607.9097
The remainder is 693 after subtracting 6517 from 7210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6930, and continue the process.

On to step 13:
If we divide 6930 by 931, we get 7 and a remainder of 413.
Use 7 as the next digit of our solution. 
Result so far: 48607.90977
Subtracting 6517 from 6930 leaves us with 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

The final outcome is 48607.90977, with a leftover of 0.000413.
