We look at the division of 99147230 by 121 
We want to figure out the number of times 99147230 can be divided by 121.

Going ahead to step 1:
If we divide 9 by 121, we get 0 and 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

Going ahead to step 2:
121 can be fit into 99 0 times, resulting in a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Fetch the next digit (1) from the dividend, attach it to 99 and continue: 991 / 121

Let's proceed to step 3:
The number 121 fits into 991 8 times, leaving a remainder of 23.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 968 from 991 and we're left with 23.
Append the next digit (4) from the dividend to 23 and continue with: 234 / 121

Advancing to step 4:
If we divide 234 by 121, we get 1 and a remainder of 113.
The next digit of our result is 1. 
Result so far: 81.0
The remainder is 113 after subtracting 121 from 234.
Include the next digit (7) from the dividend after 113, then repeat: 1137 / 121

On to step 5:
121 goes into 1137 9 times with a remainder of 48.
Put 9 as the next digit of the answer. 
Result so far: 819.0
If we subtract 1089 from 1137, we get 48.
Take the next digit (2) from the dividend and append it to 48, then repeat: 482 / 121

On to step 6:
The number 121 fits into 482 3 times, leaving a remainder of 119.
Record the quotient 3 as the next digit in the result. 
Result so far: 8193.0
Subtract 363 from 482 to get 119.
Include the next digit (3) from the dividend after 119, then repeat: 1193 / 121

Moving on to step 7:
1193 divided by 121 is 9 with a remainder of 104.
The next digit of our result is 9. 
Result so far: 81939.0
Deduct 1089 from 1193 and we're left with 104.
Fetch the next digit (0) from the dividend, attach it to 104 and continue: 1040 / 121

Let's proceed to step 8:
121 goes into 1040 8 times with a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 819398.0
If we take 968 away from 1040, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 9:
When dividing 720 by 121, we get 5 with a remainder of 115.
Record the quotient 5 as the next digit in the result. 
Result so far: 819398.5
Subtract 605 from 720 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 10:
121 can be fit into 1150 9 times, resulting in a remainder of 61.
Use 9 as the next digit of our solution. 
Result so far: 819398.59
Subtract 1089 from 1150 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 11:
When dividing 610 by 121, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 819398.595
If we subtract 605 from 610, 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.

Going ahead to step 12:
When dividing 50 by 121, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 819398.595
Deduct 0 from 50 and we're left 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.

Moving on to step 13:
500 divided by 121 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 819398.59504
Subtracting 484 from 500 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 14:
The number 121 fits into 160 1 times, leaving a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 819398.595041
The remainder is 39 after subtracting 121 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 15:
390 divided by 121 is 3 with a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 819398.5950413
Subtracting 363 from 390 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 16:
If we divide 270 by 121, we get 2 and a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 819398.59504132
Subtract 242 from 270 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 819398.59504132, and the remainder is 2.8e-08.
