We look at the division of 861351 by 91 
Let's see how many times 91 fits into 861351.

Advancing to step 1:
When dividing 8 by 91, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 91

Going ahead to step 2:
86 divided by 91 is 0 with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Append the next digit (1) from the dividend to 86 and continue with: 861 / 91

On to step 3:
91 goes into 861 9 times with a remainder of 42.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 819 from 861 leaves us with 42.
Append the next digit (3) from the dividend to 42 and continue with: 423 / 91

Advancing to step 4:
The number 91 fits into 423 4 times, leaving a remainder of 59.
Write down 4 as next digit of the result. 
Result so far: 94.0
Subtract 364 from 423 to get 59.
Bring next digit (5) of the dividend behind the 59 and repeat the process: 595 / 91

Step 5:
91 can be fit into 595 6 times, resulting in a remainder of 49.
The next digit of our result is 6. 
Result so far: 946.0
Deduct 546 from 595 and we're left with 49.
Append the next digit (1) from the dividend to 49 and continue with: 491 / 91

Step 6:
91 goes into 491 5 times with a remainder of 36.
The number 5 becomes the next digit in our result. 
Result so far: 9465.0
If we subtract 455 from 491, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 7:
When dividing 360 by 91, we get 3 with a remainder of 87.
Record the quotient 3 as the next digit in the result. 
Result so far: 9465.3
The remainder is 87 after subtracting 273 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 8:
870 divided by 91 is 9 with a remainder of 51.
The next digit of our result is 9. 
Result so far: 9465.39
If we take 819 away from 870, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 9:
510 divided by 91 is 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 9465.395
Subtracting 455 from 510 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 10:
The number 91 fits into 550 6 times, leaving a remainder of 4.
The next digit of our result is 6. 
Result so far: 9465.3956
Subtract 546 from 550 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
91 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 9465.3956
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
When dividing 400 by 91, we get 4 with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 9465.395604
Subtracting 364 from 400 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 13:
The number 91 fits into 360 3 times, leaving a remainder of 87.
The number 3 becomes the next digit in our result. 
Result so far: 9465.3956043
Subtract 273 from 360 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 14:
91 goes into 870 9 times with a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 9465.39560439
If we subtract 819 from 870, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

After the division, we end up with 9465.39560439 and a remainder of 5.1e-08.
