We look at the division of 51526053 by 865 
We want to divide 51526053 by 865.

Step 1:
The number 865 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 865

Moving on to step 2:
The number 865 fits into 51 0 times, leaving a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Fetch the next digit (5) from the dividend, attach it to 51 and continue: 515 / 865

Step 3:
If we divide 515 by 865, we get 0 and a remainder of 515.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 515 and we're left with 515.
Fetch the next digit (2) from the dividend, attach it to 515 and continue: 5152 / 865

Advancing to step 4:
The number 865 fits into 5152 5 times, leaving a remainder of 827.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 4325 from 5152 and we're left with 827.
Fetch the next digit (6) from the dividend, attach it to 827 and continue: 8276 / 865

Moving on to step 5:
If we divide 8276 by 865, we get 9 and a remainder of 491.
Write down 9 as next digit of the result. 
Result so far: 59.0
If we subtract 7785 from 8276, we get 491.
Grab the next digit (0) from the dividend, add it to 491, then carry on: 4910 / 865

On to step 6:
When dividing 4910 by 865, we get 5 with a remainder of 585.
The number 5 becomes the next digit in our result. 
Result so far: 595.0
If we subtract 4325 from 4910, we get 585.
Include the next digit (5) from the dividend after 585, then repeat: 5855 / 865

Going ahead to step 7:
When dividing 5855 by 865, we get 6 with a remainder of 665.
The number 6 becomes the next digit in our result. 
Result so far: 5956.0
The remainder is 665 after subtracting 5190 from 5855.
Append the next digit (3) from the dividend to 665 and continue with: 6653 / 865

Moving on to step 8:
The number 865 fits into 6653 7 times, leaving a remainder of 598.
The number 7 becomes the next digit in our result. 
Result so far: 59567.0
Deduct 6055 from 6653 and we're left with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Going ahead to step 9:
865 can be fit into 5980 6 times, resulting in a remainder of 790.
Put 6 as the next digit of the answer. 
Result so far: 59567.6
If we subtract 5190 from 5980, we get 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Step 10:
865 can be fit into 7900 9 times, resulting in a remainder of 115.
Use 9 as the next digit of our solution. 
Result so far: 59567.69
Subtracting 7785 from 7900 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Let's proceed to step 11:
The number 865 fits into 1150 1 times, leaving a remainder of 285.
Put 1 as the next digit of the answer. 
Result so far: 59567.691
If we take 865 away from 1150, we end up with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Step 12:
If we divide 2850 by 865, we get 3 and a remainder of 255.
Record the quotient 3 as the next digit in the result. 
Result so far: 59567.6913
The remainder is 255 after subtracting 2595 from 2850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

On to step 13:
2550 divided by 865 is 2 with a remainder of 820.
Put 2 as the next digit of the answer. 
Result so far: 59567.69132
Subtract 1730 from 2550 to get 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Going ahead to step 14:
The number 865 fits into 8200 9 times, leaving a remainder of 415.
Put 9 as the next digit of the answer. 
Result so far: 59567.691329
Subtract 7785 from 8200 to get 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Advancing to step 15:
When dividing 4150 by 865, we get 4 with a remainder of 690.
Record the quotient 4 as the next digit in the result. 
Result so far: 59567.6913294
If we subtract 3460 from 4150, we get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Moving on to step 16:
If we divide 6900 by 865, we get 7 and a remainder of 845.
Record the quotient 7 as the next digit in the result. 
Result so far: 59567.69132947
If we subtract 6055 from 6900, we get 845.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8450, and continue the process.

The final outcome is 59567.69132947, with a leftover of 8.45e-07.
