51361337 ÷ 865 
Let's see how many times 865 fits into 51361337.

Moving on to step 1:
865 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 865

Moving on to step 2:
If we divide 51 by 865, we get 0 and a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Fetch the next digit (3) from the dividend, attach it to 51 and continue: 513 / 865

Advancing to step 3:
865 goes into 513 0 times with a remainder of 513.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 513 to get 513.
Fetch the next digit (6) from the dividend, attach it to 513 and continue: 5136 / 865

Step 4:
When dividing 5136 by 865, we get 5 with a remainder of 811.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 4325 from 5136 leaves us with 811.
Take the next digit (1) from the dividend and append it to 811, then repeat: 8111 / 865

Step 5:
When dividing 8111 by 865, we get 9 with a remainder of 326.
Record the quotient 9 as the next digit in the result. 
Result so far: 59.0
The remainder is 326 after subtracting 7785 from 8111.
Include the next digit (3) from the dividend after 326, then repeat: 3263 / 865

Let's proceed to step 6:
If we divide 3263 by 865, we get 3 and a remainder of 668.
Use 3 as the next digit of our solution. 
Result so far: 593.0
The remainder is 668 after subtracting 2595 from 3263.
Fetch the next digit (3) from the dividend, attach it to 668 and continue: 6683 / 865

Going ahead to step 7:
The number 865 fits into 6683 7 times, leaving a remainder of 628.
Record the quotient 7 as the next digit in the result. 
Result so far: 5937.0
Deduct 6055 from 6683 and we're left with 628.
Grab the next digit (7) from the dividend, add it to 628, then carry on: 6287 / 865

Moving on to step 8:
The number 865 fits into 6287 7 times, leaving a remainder of 232.
Record the quotient 7 as the next digit in the result. 
Result so far: 59377.0
If we take 6055 away from 6287, we end up with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 9:
2320 divided by 865 is 2 with a remainder of 590.
Write down 2 as next digit of the result. 
Result so far: 59377.2
Subtracting 1730 from 2320 leaves us with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Moving on to step 10:
When dividing 5900 by 865, we get 6 with a remainder of 710.
Use 6 as the next digit of our solution. 
Result so far: 59377.26
Subtract 5190 from 5900 to get 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

On to step 11:
When dividing 7100 by 865, we get 8 with a remainder of 180.
Use 8 as the next digit of our solution. 
Result so far: 59377.268
If we take 6920 away from 7100, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 12:
When dividing 1800 by 865, we get 2 with a remainder of 70.
Put 2 as the next digit of the answer. 
Result so far: 59377.2682
If we take 1730 away from 1800, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 13:
When dividing 700 by 865, we get 0 with a remainder of 700.
Use 0 as the next digit of our solution. 
Result so far: 59377.2682
Subtracting 0 from 700 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

On to step 14:
When dividing 7000 by 865, we get 8 with a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 59377.268208
If we subtract 6920 from 7000, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 15:
The number 865 fits into 800 0 times, leaving a remainder of 800.
Put 0 as the next digit of the answer. 
Result so far: 59377.268208
Subtract 0 from 800 to get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Advancing to step 16:
8000 divided by 865 is 9 with a remainder of 215.
The next digit of our result is 9. 
Result so far: 59377.26820809
If we take 7785 away from 8000, we end up with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

The final outcome is 59377.26820809, with a leftover of 2.15e-07.
