We look at the division of 51616393 by 564 
Let's see how many times 564 fits into 51616393.

On to step 1:
The number 564 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 564

Step 2:
564 goes into 51 0 times with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Bring next digit (6) of the dividend behind the 51 and repeat the process: 516 / 564

Step 3:
The number 564 fits into 516 0 times, leaving a remainder of 516.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 516 after subtracting 0 from 516.
Include the next digit (1) from the dividend after 516, then repeat: 5161 / 564

On to step 4:
If we divide 5161 by 564, we get 9 and a remainder of 85.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 5076 away from 5161, we end up with 85.
Append the next digit (6) from the dividend to 85 and continue with: 856 / 564

On to step 5:
564 goes into 856 1 times with a remainder of 292.
Use 1 as the next digit of our solution. 
Result so far: 91.0
If we subtract 564 from 856, we get 292.
Grab the next digit (3) from the dividend, add it to 292, then carry on: 2923 / 564

Going ahead to step 6:
If we divide 2923 by 564, we get 5 and a remainder of 103.
Put 5 as the next digit of the answer. 
Result so far: 915.0
Subtract 2820 from 2923 to get 103.
Fetch the next digit (9) from the dividend, attach it to 103 and continue: 1039 / 564

Moving on to step 7:
When dividing 1039 by 564, we get 1 with a remainder of 475.
The number 1 becomes the next digit in our result. 
Result so far: 9151.0
Subtracting 564 from 1039 leaves us with 475.
Append the next digit (3) from the dividend to 475 and continue with: 4753 / 564

Moving on to step 8:
The number 564 fits into 4753 8 times, leaving a remainder of 241.
Write down 8 as next digit of the result. 
Result so far: 91518.0
The remainder is 241 after subtracting 4512 from 4753.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Advancing to step 9:
The number 564 fits into 2410 4 times, leaving a remainder of 154.
Record the quotient 4 as the next digit in the result. 
Result so far: 91518.4
Deduct 2256 from 2410 and we're left with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

On to step 10:
If we divide 1540 by 564, we get 2 and a remainder of 412.
The number 2 becomes the next digit in our result. 
Result so far: 91518.42
If we take 1128 away from 1540, we end up with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

On to step 11:
When dividing 4120 by 564, we get 7 with a remainder of 172.
Write down 7 as next digit of the result. 
Result so far: 91518.427
Subtract 3948 from 4120 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 12:
When dividing 1720 by 564, we get 3 with a remainder of 28.
The next digit of our result is 3. 
Result so far: 91518.4273
If we take 1692 away from 1720, we end up 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.

Going ahead to step 13:
If we divide 280 by 564, we get 0 and a remainder of 280.
The number 0 becomes the next digit in our result. 
Result so far: 91518.4273
The remainder is 280 after subtracting 0 from 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 14:
If we divide 2800 by 564, we get 4 and a remainder of 544.
The number 4 becomes the next digit in our result. 
Result so far: 91518.427304
Subtracting 2256 from 2800 leaves us with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Going ahead to step 15:
The number 564 fits into 5440 9 times, leaving a remainder of 364.
Put 9 as the next digit of the answer. 
Result so far: 91518.4273049
If we take 5076 away from 5440, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Going ahead to step 16:
564 can be fit into 3640 6 times, resulting in a remainder of 256.
Write down 6 as next digit of the result. 
Result so far: 91518.42730496
Subtract 3384 from 3640 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

The final outcome is 91518.42730496, with a leftover of 2.56e-07.
