We look at the division of 71386321 by 566 
We want to divide 71386321 by 566.

On to step 1:
When dividing 7 by 566, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 566

Step 2:
The number 566 fits into 71 0 times, leaving a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Grab the next digit (3) from the dividend, add it to 71, then carry on: 713 / 566

Advancing to step 3:
If we divide 713 by 566, we get 1 and a remainder of 147.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 566 from 713 to get 147.
Bring next digit (8) of the dividend behind the 147 and repeat the process: 1478 / 566

On to step 4:
The number 566 fits into 1478 2 times, leaving a remainder of 346.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 1132 from 1478, we get 346.
Include the next digit (6) from the dividend after 346, then repeat: 3466 / 566

Moving on to step 5:
The number 566 fits into 3466 6 times, leaving a remainder of 70.
Use 6 as the next digit of our solution. 
Result so far: 126.0
The remainder is 70 after subtracting 3396 from 3466.
Take the next digit (3) from the dividend and append it to 70, then repeat: 703 / 566

Advancing to step 6:
When dividing 703 by 566, we get 1 with a remainder of 137.
Record the quotient 1 as the next digit in the result. 
Result so far: 1261.0
If we subtract 566 from 703, we get 137.
Append the next digit (2) from the dividend to 137 and continue with: 1372 / 566

Going ahead to step 7:
1372 divided by 566 is 2 with a remainder of 240.
Record the quotient 2 as the next digit in the result. 
Result so far: 12612.0
Deduct 1132 from 1372 and we're left with 240.
Append the next digit (1) from the dividend to 240 and continue with: 2401 / 566

Step 8:
If we divide 2401 by 566, we get 4 and a remainder of 137.
Put 4 as the next digit of the answer. 
Result so far: 126124.0
Subtracting 2264 from 2401 leaves us with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Step 9:
When dividing 1370 by 566, we get 2 with a remainder of 238.
Use 2 as the next digit of our solution. 
Result so far: 126124.2
The remainder is 238 after subtracting 1132 from 1370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 10:
566 can be fit into 2380 4 times, resulting in a remainder of 116.
Record the quotient 4 as the next digit in the result. 
Result so far: 126124.24
The remainder is 116 after subtracting 2264 from 2380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 11:
The number 566 fits into 1160 2 times, leaving a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 126124.242
Deduct 1132 from 1160 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 12:
When dividing 280 by 566, we get 0 with a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 126124.242
Subtract 0 from 280 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 13:
If we divide 2800 by 566, we get 4 and a remainder of 536.
The number 4 becomes the next digit in our result. 
Result so far: 126124.24204
The remainder is 536 after subtracting 2264 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Let's proceed to step 14:
5360 divided by 566 is 9 with a remainder of 266.
Record the quotient 9 as the next digit in the result. 
Result so far: 126124.242049
If we take 5094 away from 5360, we end up with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Going ahead to step 15:
If we divide 2660 by 566, we get 4 and a remainder of 396.
Record the quotient 4 as the next digit in the result. 
Result so far: 126124.2420494
Subtract 2264 from 2660 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Step 16:
When dividing 3960 by 566, we get 6 with a remainder of 564.
Use 6 as the next digit of our solution. 
Result so far: 126124.24204946
Subtract 3396 from 3960 to get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

The final result is 126124.24204946 with a remainder of 5.64e-07.
