988215 ÷ 91 
We want to divide 988215 by 91.

Advancing to step 1:
When dividing 9 by 91, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 91

On to step 2:
98 divided by 91 is 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 7 after subtracting 91 from 98.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 91

Step 3:
91 can be fit into 78 0 times, resulting in a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 78 and we're left with 78.
Bring next digit (2) of the dividend behind the 78 and repeat the process: 782 / 91

Going ahead to step 4:
91 goes into 782 8 times with a remainder of 54.
The next digit of our result is 8. 
Result so far: 108.0
Deduct 728 from 782 and we're left with 54.
Append the next digit (1) from the dividend to 54 and continue with: 541 / 91

Step 5:
The number 91 fits into 541 5 times, leaving a remainder of 86.
Record the quotient 5 as the next digit in the result. 
Result so far: 1085.0
Subtracting 455 from 541 leaves us with 86.
Take the next digit (5) from the dividend and append it to 86, then repeat: 865 / 91

Going ahead to step 6:
When dividing 865 by 91, we get 9 with a remainder of 46.
The next digit of our result is 9. 
Result so far: 10859.0
If we subtract 819 from 865, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 7:
If we divide 460 by 91, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 10859.5
If we subtract 455 from 460, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
If we divide 50 by 91, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 10859.5
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
If we divide 500 by 91, we get 5 and a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 10859.505
Subtracting 455 from 500 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 10:
When dividing 450 by 91, we get 4 with a remainder of 86.
Record the quotient 4 as the next digit in the result. 
Result so far: 10859.5054
If we take 364 away from 450, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 11:
The number 91 fits into 860 9 times, leaving a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 10859.50549
If we subtract 819 from 860, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 12:
If we divide 410 by 91, we get 4 and a remainder of 46.
The next digit of our result is 4. 
Result so far: 10859.505494
Subtract 364 from 410 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 13:
If we divide 460 by 91, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 10859.5054945
Subtract 455 from 460 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 14:
91 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 10859.5054945
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final outcome is 10859.5054945, with a leftover of 5e-08.
