79412361 ÷ 121 
We want to divide 79412361 by 121.

On to step 1:
If we divide 7 by 121, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 121

Advancing to step 2:
When dividing 79 by 121, we get 0 with a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Fetch the next digit (4) from the dividend, attach it to 79 and continue: 794 / 121

On to step 3:
If we divide 794 by 121, we get 6 and a remainder of 68.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 726 from 794, we get 68.
Grab the next digit (1) from the dividend, add it to 68, then carry on: 681 / 121

Advancing to step 4:
If we divide 681 by 121, we get 5 and a remainder of 76.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
The remainder is 76 after subtracting 605 from 681.
Include the next digit (2) from the dividend after 76, then repeat: 762 / 121

Going ahead to step 5:
If we divide 762 by 121, we get 6 and a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 656.0
Subtract 726 from 762 to get 36.
Take the next digit (3) from the dividend and append it to 36, then repeat: 363 / 121

Going ahead to step 6:
The number 121 fits into 363 3 times, leaving a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 6563.0
If we take 363 away from 363, we end up with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 121

Going ahead to step 7:
121 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 65630.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 121

On to step 8:
61 divided by 121 is 0 with a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 656300.0
Subtract 0 from 61 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.

Moving on to step 9:
121 goes into 610 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 656300.5
The remainder is 5 after subtracting 605 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 10:
50 divided by 121 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 656300.5
Subtracting 0 from 50 leaves us 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 11:
500 divided by 121 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 656300.504
If we take 484 away from 500, we end up 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.

Going ahead to step 12:
The number 121 fits into 160 1 times, leaving a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 656300.5041
If we take 121 away from 160, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 13:
121 can be fit into 390 3 times, resulting in a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 656300.50413
If we take 363 away from 390, we end up 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.

Advancing to step 14:
121 goes into 270 2 times with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 656300.504132
Subtracting 242 from 270 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 15:
280 divided by 121 is 2 with a remainder of 38.
The next digit of our result is 2. 
Result so far: 656300.5041322
If we take 242 away from 280, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final result is 656300.5041322 with a remainder of 3.8e-07.
