78212151 divided by 568 
We're looking to find how many times 568 goes into 78212151.

Step 1:
When dividing 7 by 568, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 568

On to step 2:
568 can be fit into 78 0 times, resulting in a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Bring next digit (2) of the dividend behind the 78 and repeat the process: 782 / 568

On to step 3:
When dividing 782 by 568, we get 1 with a remainder of 214.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 214 after subtracting 568 from 782.
Include the next digit (1) from the dividend after 214, then repeat: 2141 / 568

Step 4:
If we divide 2141 by 568, we get 3 and a remainder of 437.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 1704 from 2141 to get 437.
Grab the next digit (2) from the dividend, add it to 437, then carry on: 4372 / 568

On to step 5:
4372 divided by 568 is 7 with a remainder of 396.
Put 7 as the next digit of the answer. 
Result so far: 137.0
Subtracting 3976 from 4372 leaves us with 396.
Take the next digit (1) from the dividend and append it to 396, then repeat: 3961 / 568

On to step 6:
568 can be fit into 3961 6 times, resulting in a remainder of 553.
Write down 6 as next digit of the result. 
Result so far: 1376.0
Subtracting 3408 from 3961 leaves us with 553.
Include the next digit (5) from the dividend after 553, then repeat: 5535 / 568

Going ahead to step 7:
568 can be fit into 5535 9 times, resulting in a remainder of 423.
Write down 9 as next digit of the result. 
Result so far: 13769.0
If we take 5112 away from 5535, we end up with 423.
Append the next digit (1) from the dividend to 423 and continue with: 4231 / 568

Step 8:
4231 divided by 568 is 7 with a remainder of 255.
Record the quotient 7 as the next digit in the result. 
Result so far: 137697.0
The remainder is 255 after subtracting 3976 from 4231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Advancing to step 9:
568 goes into 2550 4 times with a remainder of 278.
Use 4 as the next digit of our solution. 
Result so far: 137697.4
If we take 2272 away from 2550, we end up with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Advancing to step 10:
When dividing 2780 by 568, we get 4 with a remainder of 508.
Record the quotient 4 as the next digit in the result. 
Result so far: 137697.44
The remainder is 508 after subtracting 2272 from 2780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

The final result is 137697.44 with a remainder of 0.508.
