We look at the division of 81376336 by 121 
We want to divide 81376336 by 121.

Step 1:
8 divided by 121 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 121

On to step 2:
121 can be fit into 81 0 times, resulting in a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Grab the next digit (3) from the dividend, add it to 81, then carry on: 813 / 121

Advancing to step 3:
121 goes into 813 6 times with a remainder of 87.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 726 from 813 leaves us with 87.
Include the next digit (7) from the dividend after 87, then repeat: 877 / 121

Moving on to step 4:
When dividing 877 by 121, we get 7 with a remainder of 30.
Put 7 as the next digit of the answer. 
Result so far: 67.0
If we subtract 847 from 877, we get 30.
Fetch the next digit (6) from the dividend, attach it to 30 and continue: 306 / 121

Step 5:
306 divided by 121 is 2 with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 672.0
Subtract 242 from 306 to get 64.
Include the next digit (3) from the dividend after 64, then repeat: 643 / 121

Let's proceed to step 6:
121 can be fit into 643 5 times, resulting in a remainder of 38.
The next digit of our result is 5. 
Result so far: 6725.0
If we take 605 away from 643, we end up with 38.
Include the next digit (3) from the dividend after 38, then repeat: 383 / 121

Let's proceed to step 7:
383 divided by 121 is 3 with a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 67253.0
Deduct 363 from 383 and we're left with 20.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 121

Going ahead to step 8:
The number 121 fits into 206 1 times, leaving a remainder of 85.
Put 1 as the next digit of the answer. 
Result so far: 672531.0
If we take 121 away from 206, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 9:
121 can be fit into 850 7 times, resulting in a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 672531.7
The remainder is 3 after subtracting 847 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
The number 121 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 672531.7
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
The number 121 fits into 300 2 times, leaving a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 672531.702
Subtracting 242 from 300 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 12:
If we divide 580 by 121, we get 4 and a remainder of 96.
Write down 4 as next digit of the result. 
Result so far: 672531.7024
If we take 484 away from 580, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 13:
The number 121 fits into 960 7 times, leaving a remainder of 113.
Use 7 as the next digit of our solution. 
Result so far: 672531.70247
Subtract 847 from 960 to get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Let's proceed to step 14:
If we divide 1130 by 121, we get 9 and a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 672531.702479
Deduct 1089 from 1130 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 15:
The number 121 fits into 410 3 times, leaving a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 672531.7024793
The remainder is 47 after subtracting 363 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 16:
121 can be fit into 470 3 times, resulting in a remainder of 107.
The number 3 becomes the next digit in our result. 
Result so far: 672531.70247933
Subtract 363 from 470 to get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Our division results in 672531.70247933 with a remaining 1.07e-07.
