891360 ÷ 86 
We're looking to find how many times 86 goes into 891360.

Step 1:
8 divided by 86 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 86

Step 2:
The number 86 fits into 89 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 86 from 89 to get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 86

Step 3:
86 goes into 31 0 times with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 31, we end up with 31.
Append the next digit (3) from the dividend to 31 and continue with: 313 / 86

Advancing to step 4:
313 divided by 86 is 3 with a remainder of 55.
Use 3 as the next digit of our solution. 
Result so far: 103.0
Deduct 258 from 313 and we're left with 55.
Grab the next digit (6) from the dividend, add it to 55, then carry on: 556 / 86

Advancing to step 5:
When dividing 556 by 86, we get 6 with a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 1036.0
Subtract 516 from 556 to get 40.
Fetch the next digit (0) from the dividend, attach it to 40 and continue: 400 / 86

Let's proceed to step 6:
The number 86 fits into 400 4 times, leaving a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 10364.0
If we take 344 away from 400, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 7:
86 can be fit into 560 6 times, resulting in a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 10364.6
If we subtract 516 from 560, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 8:
The number 86 fits into 440 5 times, leaving a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 10364.65
Deduct 430 from 440 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
86 goes into 100 1 times with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 10364.651
The remainder is 14 after subtracting 86 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
If we divide 140 by 86, we get 1 and a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 10364.6511
Subtract 86 from 140 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final outcome is 10364.6511, with a leftover of 0.00054.
