We look at the division of 9913430 by 121 
We're looking to find how many times 121 goes into 9913430.

Step 1:
121 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 121

Step 2:
121 goes into 99 0 times with a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Grab the next digit (1) from the dividend, add it to 99, then carry on: 991 / 121

Moving on to step 3:
121 goes into 991 8 times with a remainder of 23.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 968 from 991 leaves us with 23.
Append the next digit (3) from the dividend to 23 and continue with: 233 / 121

Let's proceed to step 4:
The number 121 fits into 233 1 times, leaving a remainder of 112.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
If we take 121 away from 233, we end up with 112.
Include the next digit (4) from the dividend after 112, then repeat: 1124 / 121

Step 5:
When dividing 1124 by 121, we get 9 with a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 819.0
If we take 1089 away from 1124, we end up with 35.
Take the next digit (3) from the dividend and append it to 35, then repeat: 353 / 121

Moving on to step 6:
If we divide 353 by 121, we get 2 and a remainder of 111.
Write down 2 as next digit of the result. 
Result so far: 8192.0
Subtracting 242 from 353 leaves us with 111.
Include the next digit (0) from the dividend after 111, then repeat: 1110 / 121

Let's proceed to step 7:
1110 divided by 121 is 9 with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 81929.0
Subtract 1089 from 1110 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.

Let's proceed to step 8:
When dividing 210 by 121, we get 1 with a remainder of 89.
Write down 1 as next digit of the result. 
Result so far: 81929.1
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.

Step 9:
The number 121 fits into 890 7 times, leaving a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 81929.17
Deduct 847 from 890 and we're left 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.

Going ahead to step 10:
430 divided by 121 is 3 with a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 81929.173
Deduct 363 from 430 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 11:
121 can be fit into 670 5 times, resulting in a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 81929.1735
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.

Step 12:
When dividing 650 by 121, we get 5 with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 81929.17355
Deduct 605 from 650 and we're left 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.

Our division results in 81929.17355 with a remaining 4.5e-05.
