We divide 988910 by 91
We want to figure out the number of times 988910 can be divided by 91.

Moving on to step 1:
The number 91 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 91

Step 2:
When dividing 98 by 91, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 7 after subtracting 91 from 98.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 91

Going ahead to step 3:
When dividing 78 by 91, we get 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 78 after subtracting 0 from 78.
Bring next digit (9) of the dividend behind the 78 and repeat the process: 789 / 91

Let's proceed to step 4:
If we divide 789 by 91, we get 8 and a remainder of 61.
Write down 8 as next digit of the result. 
Result so far: 108.0
If we take 728 away from 789, we end up with 61.
Take the next digit (1) from the dividend and append it to 61, then repeat: 611 / 91

On to step 5:
91 can be fit into 611 6 times, resulting in a remainder of 65.
The next digit of our result is 6. 
Result so far: 1086.0
If we take 546 away from 611, we end up with 65.
Append the next digit (0) from the dividend to 65 and continue with: 650 / 91

Advancing to step 6:
The number 91 fits into 650 7 times, leaving a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 10867.0
Subtract 637 from 650 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
The number 91 fits into 130 1 times, leaving a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 10867.1
If we take 91 away from 130, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 8:
91 goes into 390 4 times with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 10867.14
Subtract 364 from 390 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
When dividing 260 by 91, we get 2 with a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 10867.142
If we take 182 away from 260, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 10:
91 can be fit into 780 8 times, resulting in a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 10867.1428
Subtracting 728 from 780 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 11:
The number 91 fits into 520 5 times, leaving a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 10867.14285
If we take 455 away from 520, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 12:
If we divide 650 by 91, we get 7 and a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 10867.142857
The remainder is 13 after subtracting 637 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 13:
91 can be fit into 130 1 times, resulting in a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 10867.1428571
If we subtract 91 from 130, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 14:
91 goes into 390 4 times with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 10867.14285714
The remainder is 26 after subtracting 364 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Our division results in 10867.14285714 with a remaining 2.6e-08.
