We're dividing 86891465 by 907 
We want to divide 86891465 by 907.

On to step 1:
When dividing 8 by 907, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 907

Going ahead to step 2:
907 can be fit into 86 0 times, resulting in a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Grab the next digit (8) from the dividend, add it to 86, then carry on: 868 / 907

Let's proceed to step 3:
The number 907 fits into 868 0 times, leaving a remainder of 868.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 868 leaves us with 868.
Take the next digit (9) from the dividend and append it to 868, then repeat: 8689 / 907

Step 4:
When dividing 8689 by 907, we get 9 with a remainder of 526.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 8163 from 8689, we get 526.
Include the next digit (1) from the dividend after 526, then repeat: 5261 / 907

Step 5:
If we divide 5261 by 907, we get 5 and a remainder of 726.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
If we take 4535 away from 5261, we end up with 726.
Take the next digit (4) from the dividend and append it to 726, then repeat: 7264 / 907

On to step 6:
7264 divided by 907 is 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 958.0
The remainder is 8 after subtracting 7256 from 7264.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 907

Let's proceed to step 7:
The number 907 fits into 86 0 times, leaving a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 9580.0
If we subtract 0 from 86, we get 86.
Take the next digit (5) from the dividend and append it to 86, then repeat: 865 / 907

Step 8:
When dividing 865 by 907, we get 0 with a remainder of 865.
Put 0 as the next digit of the answer. 
Result so far: 95800.0
If we subtract 0 from 865, we get 865.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8650, and continue the process.

Advancing to step 9:
If we divide 8650 by 907, we get 9 and a remainder of 487.
Use 9 as the next digit of our solution. 
Result so far: 95800.9
If we subtract 8163 from 8650, we get 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

Let's proceed to step 10:
When dividing 4870 by 907, we get 5 with a remainder of 335.
Record the quotient 5 as the next digit in the result. 
Result so far: 95800.95
The remainder is 335 after subtracting 4535 from 4870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Let's proceed to step 11:
The number 907 fits into 3350 3 times, leaving a remainder of 629.
Record the quotient 3 as the next digit in the result. 
Result so far: 95800.953
Subtract 2721 from 3350 to get 629.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6290, and continue the process.

Moving on to step 12:
6290 divided by 907 is 6 with a remainder of 848.
The number 6 becomes the next digit in our result. 
Result so far: 95800.9536
If we take 5442 away from 6290, we end up with 848.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8480, and continue the process.

On to step 13:
The number 907 fits into 8480 9 times, leaving a remainder of 317.
Put 9 as the next digit of the answer. 
Result so far: 95800.95369
The remainder is 317 after subtracting 8163 from 8480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Let's proceed to step 14:
The number 907 fits into 3170 3 times, leaving a remainder of 449.
Record the quotient 3 as the next digit in the result. 
Result so far: 95800.953693
Subtracting 2721 from 3170 leaves us with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Let's proceed to step 15:
The number 907 fits into 4490 4 times, leaving a remainder of 862.
The number 4 becomes the next digit in our result. 
Result so far: 95800.9536934
Deduct 3628 from 4490 and we're left with 862.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8620, and continue the process.

Advancing to step 16:
If we divide 8620 by 907, we get 9 and a remainder of 457.
Put 9 as the next digit of the answer. 
Result so far: 95800.95369349
The remainder is 457 after subtracting 8163 from 8620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

The final outcome is 95800.95369349, with a leftover of 4.57e-07.
