We look at the division of 91702018 by 121 
Our goal is to divide 91702018 by 121.

On to step 1:
121 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 121

Going ahead to step 2:
121 can be fit into 91 0 times, resulting in a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Bring next digit (7) of the dividend behind the 91 and repeat the process: 917 / 121

Going ahead to step 3:
121 can be fit into 917 7 times, resulting in a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 847 from 917 and we're left with 70.
Fetch the next digit (0) from the dividend, attach it to 70 and continue: 700 / 121

Going ahead to step 4:
700 divided by 121 is 5 with a remainder of 95.
Use 5 as the next digit of our solution. 
Result so far: 75.0
Deduct 605 from 700 and we're left with 95.
Grab the next digit (2) from the dividend, add it to 95, then carry on: 952 / 121

Advancing to step 5:
952 divided by 121 is 7 with a remainder of 105.
Put 7 as the next digit of the answer. 
Result so far: 757.0
The remainder is 105 after subtracting 847 from 952.
Bring next digit (0) of the dividend behind the 105 and repeat the process: 1050 / 121

Let's proceed to step 6:
If we divide 1050 by 121, we get 8 and a remainder of 82.
The next digit of our result is 8. 
Result so far: 7578.0
If we take 968 away from 1050, we end up with 82.
Take the next digit (1) from the dividend and append it to 82, then repeat: 821 / 121

Step 7:
121 can be fit into 821 6 times, resulting in a remainder of 95.
Use 6 as the next digit of our solution. 
Result so far: 75786.0
Subtracting 726 from 821 leaves us with 95.
Include the next digit (8) from the dividend after 95, then repeat: 958 / 121

Going ahead to step 8:
121 can be fit into 958 7 times, resulting in a remainder of 111.
Write down 7 as next digit of the result. 
Result so far: 757867.0
Subtract 847 from 958 to get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Going ahead to step 9:
The number 121 fits into 1110 9 times, leaving a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 757867.9
The remainder is 21 after subtracting 1089 from 1110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 10:
When dividing 210 by 121, we get 1 with a remainder of 89.
Put 1 as the next digit of the answer. 
Result so far: 757867.91
If we take 121 away from 210, we end up with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Let's proceed to step 11:
The number 121 fits into 890 7 times, leaving a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 757867.917
If we take 847 away from 890, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 12:
121 can be fit into 430 3 times, resulting in a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 757867.9173
The remainder is 67 after subtracting 363 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 13:
The number 121 fits into 670 5 times, leaving a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 757867.91735
The remainder is 65 after subtracting 605 from 670.
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 14:
If we divide 650 by 121, we get 5 and a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 757867.917355
The remainder is 45 after subtracting 605 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

After the division, we end up with 757867.917355 and a remainder of 4.5e-06.
