83957839 divided by 564 
Our goal is to divide 83957839 by 564.

Step 1:
564 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 564

Moving on to step 2:
564 goes into 83 0 times with a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Bring next digit (9) of the dividend behind the 83 and repeat the process: 839 / 564

Going ahead to step 3:
564 can be fit into 839 1 times, resulting in a remainder of 275.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 564 from 839 to get 275.
Append the next digit (5) from the dividend to 275 and continue with: 2755 / 564

Advancing to step 4:
2755 divided by 564 is 4 with a remainder of 499.
The next digit of our result is 4. 
Result so far: 14.0
If we subtract 2256 from 2755, we get 499.
Take the next digit (7) from the dividend and append it to 499, then repeat: 4997 / 564

Going ahead to step 5:
4997 divided by 564 is 8 with a remainder of 485.
Put 8 as the next digit of the answer. 
Result so far: 148.0
If we take 4512 away from 4997, we end up with 485.
Grab the next digit (8) from the dividend, add it to 485, then carry on: 4858 / 564

Advancing to step 6:
4858 divided by 564 is 8 with a remainder of 346.
Record the quotient 8 as the next digit in the result. 
Result so far: 1488.0
If we take 4512 away from 4858, we end up with 346.
Append the next digit (3) from the dividend to 346 and continue with: 3463 / 564

Moving on to step 7:
When dividing 3463 by 564, we get 6 with a remainder of 79.
The next digit of our result is 6. 
Result so far: 14886.0
Subtracting 3384 from 3463 leaves us with 79.
Fetch the next digit (9) from the dividend, attach it to 79 and continue: 799 / 564

On to step 8:
564 goes into 799 1 times with a remainder of 235.
Use 1 as the next digit of our solution. 
Result so far: 148861.0
Subtract 564 from 799 to get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Moving on to step 9:
If we divide 2350 by 564, we get 4 and a remainder of 94.
The number 4 becomes the next digit in our result. 
Result so far: 148861.4
If we subtract 2256 from 2350, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 10:
The number 564 fits into 940 1 times, leaving a remainder of 376.
The next digit of our result is 1. 
Result so far: 148861.41
Subtract 564 from 940 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.

Advancing to step 11:
564 can be fit into 3760 6 times, resulting in a remainder of 376.
The number 6 becomes the next digit in our result. 
Result so far: 148861.416
Subtracting 3384 from 3760 leaves us with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Going ahead to step 12:
The number 564 fits into 3760 6 times, leaving a remainder of 376.
Write down 6 as next digit of the result. 
Result so far: 148861.4166
The remainder is 376 after subtracting 3384 from 3760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

The final outcome is 148861.4166, with a leftover of 0.00376.
