78401361 divided by 566 
We want to divide 78401361 by 566.

Moving on to step 1:
The number 566 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 566

Let's proceed to step 2:
78 divided by 566 is 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Bring next digit (4) of the dividend behind the 78 and repeat the process: 784 / 566

Going ahead to step 3:
566 goes into 784 1 times with a remainder of 218.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 566 away from 784, we end up with 218.
Fetch the next digit (0) from the dividend, attach it to 218 and continue: 2180 / 566

Step 4:
566 can be fit into 2180 3 times, resulting in a remainder of 482.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 1698 from 2180, we get 482.
Include the next digit (1) from the dividend after 482, then repeat: 4821 / 566

On to step 5:
566 can be fit into 4821 8 times, resulting in a remainder of 293.
Record the quotient 8 as the next digit in the result. 
Result so far: 138.0
The remainder is 293 after subtracting 4528 from 4821.
Append the next digit (3) from the dividend to 293 and continue with: 2933 / 566

On to step 6:
If we divide 2933 by 566, we get 5 and a remainder of 103.
Put 5 as the next digit of the answer. 
Result so far: 1385.0
If we subtract 2830 from 2933, we get 103.
Append the next digit (6) from the dividend to 103 and continue with: 1036 / 566

Moving on to step 7:
The number 566 fits into 1036 1 times, leaving a remainder of 470.
Record the quotient 1 as the next digit in the result. 
Result so far: 13851.0
If we subtract 566 from 1036, we get 470.
Grab the next digit (1) from the dividend, add it to 470, then carry on: 4701 / 566

Going ahead to step 8:
When dividing 4701 by 566, we get 8 with a remainder of 173.
Record the quotient 8 as the next digit in the result. 
Result so far: 138518.0
Subtracting 4528 from 4701 leaves us with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

On to step 9:
566 goes into 1730 3 times with a remainder of 32.
Put 3 as the next digit of the answer. 
Result so far: 138518.3
Subtract 1698 from 1730 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
The number 566 fits into 320 0 times, leaving a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 138518.3
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 11:
The number 566 fits into 3200 5 times, leaving a remainder of 370.
Use 5 as the next digit of our solution. 
Result so far: 138518.305
Subtract 2830 from 3200 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Advancing to step 12:
566 can be fit into 3700 6 times, resulting in a remainder of 304.
Use 6 as the next digit of our solution. 
Result so far: 138518.3056
If we subtract 3396 from 3700, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 13:
The number 566 fits into 3040 5 times, leaving a remainder of 210.
Use 5 as the next digit of our solution. 
Result so far: 138518.30565
If we take 2830 away from 3040, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 14:
2100 divided by 566 is 3 with a remainder of 402.
Record the quotient 3 as the next digit in the result. 
Result so far: 138518.305653
Subtract 1698 from 2100 to get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

On to step 15:
When dividing 4020 by 566, we get 7 with a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 138518.3056537
Deduct 3962 from 4020 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 16:
580 divided by 566 is 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 138518.30565371
Subtracting 566 from 580 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 138518.30565371 with a remaining 1.4e-08.
