91081215 ÷ 101 
We want to divide 91081215 by 101.

Let's proceed to step 1:
If we divide 9 by 101, we get 0 and 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.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 101

Going ahead to step 2:
When dividing 91 by 101, we get 0 with a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Take the next digit (0) from the dividend and append it to 91, then repeat: 910 / 101

Advancing to step 3:
910 divided by 101 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 909 from 910, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 101

Advancing to step 4:
101 goes into 18 0 times with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 90.0
If we subtract 0 from 18, we get 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 101

Step 5:
The number 101 fits into 181 1 times, leaving a remainder of 80.
Write down 1 as next digit of the result. 
Result so far: 901.0
The remainder is 80 after subtracting 101 from 181.
Take the next digit (2) from the dividend and append it to 80, then repeat: 802 / 101

Let's proceed to step 6:
If we divide 802 by 101, we get 7 and a remainder of 95.
Put 7 as the next digit of the answer. 
Result so far: 9017.0
Subtracting 707 from 802 leaves us with 95.
Take the next digit (1) from the dividend and append it to 95, then repeat: 951 / 101

On to step 7:
When dividing 951 by 101, we get 9 with a remainder of 42.
Put 9 as the next digit of the answer. 
Result so far: 90179.0
Subtract 909 from 951 to get 42.
Take the next digit (5) from the dividend and append it to 42, then repeat: 425 / 101

Going ahead to step 8:
If we divide 425 by 101, we get 4 and a remainder of 21.
Record the quotient 4 as the next digit in the result. 
Result so far: 901794.0
Subtract 404 from 425 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 9:
If we divide 210 by 101, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 901794.2
The remainder is 8 after subtracting 202 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
80 divided by 101 is 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 901794.2
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 11:
The number 101 fits into 800 7 times, leaving a remainder of 93.
Use 7 as the next digit of our solution. 
Result so far: 901794.207
The remainder is 93 after subtracting 707 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Advancing to step 12:
930 divided by 101 is 9 with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 901794.2079
Deduct 909 from 930 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 13:
The number 101 fits into 210 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 901794.20792
Subtract 202 from 210 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 14:
If we divide 80 by 101, we get 0 and a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 901794.20792
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 15:
101 can be fit into 800 7 times, resulting in a remainder of 93.
The number 7 becomes the next digit in our result. 
Result so far: 901794.2079207
Subtracting 707 from 800 leaves us with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Going ahead to step 16:
101 can be fit into 930 9 times, resulting in a remainder of 21.
The next digit of our result is 9. 
Result so far: 901794.20792079
Subtract 909 from 930 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

In conclusion, the division gives 901794.20792079 with a balance of 2.1e-08.
