We divide 77932872 by 121
We want to divide 77932872 by 121.

Step 1:
When dividing 7 by 121, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 121

On to step 2:
121 can be fit into 77 0 times, resulting in a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Include the next digit (9) from the dividend after 77, then repeat: 779 / 121

Going ahead to step 3:
When dividing 779 by 121, we get 6 with a remainder of 53.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 53 after subtracting 726 from 779.
Grab the next digit (3) from the dividend, add it to 53, then carry on: 533 / 121

Going ahead to step 4:
When dividing 533 by 121, we get 4 with a remainder of 49.
Put 4 as the next digit of the answer. 
Result so far: 64.0
If we subtract 484 from 533, we get 49.
Grab the next digit (2) from the dividend, add it to 49, then carry on: 492 / 121

Advancing to step 5:
When dividing 492 by 121, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 644.0
If we take 484 away from 492, we end up with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 121

Let's proceed to step 6:
88 divided by 121 is 0 with a remainder of 88.
The next digit of our result is 0. 
Result so far: 6440.0
Deduct 0 from 88 and we're left with 88.
Bring next digit (7) of the dividend behind the 88 and repeat the process: 887 / 121

Step 7:
121 can be fit into 887 7 times, resulting in a remainder of 40.
The next digit of our result is 7. 
Result so far: 64407.0
If we take 847 away from 887, we end up with 40.
Bring next digit (2) of the dividend behind the 40 and repeat the process: 402 / 121

Let's proceed to step 8:
If we divide 402 by 121, we get 3 and a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 644073.0
Subtracting 363 from 402 leaves us 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.

Moving on to step 9:
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: 644073.3
The remainder is 27 after subtracting 363 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 10:
If we divide 270 by 121, we get 2 and a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 644073.32
If we subtract 242 from 270, we 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.

Step 11:
When dividing 280 by 121, we get 2 with a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 644073.322
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.

Our division results in 644073.322 with a remaining 0.0038.
