Let's divide 39557089 by 122
We want to divide 39557089 by 122.

Advancing to step 1:
If we divide 3 by 122, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 122

Going ahead to step 2:
122 can be fit into 39 0 times, resulting in a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Include the next digit (5) from the dividend after 39, then repeat: 395 / 122

Moving on to step 3:
122 goes into 395 3 times with a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 366 away from 395, we end up with 29.
Fetch the next digit (5) from the dividend, attach it to 29 and continue: 295 / 122

On to step 4:
295 divided by 122 is 2 with a remainder of 51.
Use 2 as the next digit of our solution. 
Result so far: 32.0
If we take 244 away from 295, we end up with 51.
Grab the next digit (7) from the dividend, add it to 51, then carry on: 517 / 122

Advancing to step 5:
122 goes into 517 4 times with a remainder of 29.
Put 4 as the next digit of the answer. 
Result so far: 324.0
Subtracting 488 from 517 leaves us with 29.
Grab the next digit (0) from the dividend, add it to 29, then carry on: 290 / 122

Going ahead to step 6:
122 can be fit into 290 2 times, resulting in a remainder of 46.
Put 2 as the next digit of the answer. 
Result so far: 3242.0
Deduct 244 from 290 and we're left with 46.
Fetch the next digit (8) from the dividend, attach it to 46 and continue: 468 / 122

On to step 7:
122 goes into 468 3 times with a remainder of 102.
Write down 3 as next digit of the result. 
Result so far: 32423.0
Deduct 366 from 468 and we're left with 102.
Take the next digit (9) from the dividend and append it to 102, then repeat: 1029 / 122

Moving on to step 8:
122 goes into 1029 8 times with a remainder of 53.
Put 8 as the next digit of the answer. 
Result so far: 324238.0
If we take 976 away from 1029, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 9:
530 divided by 122 is 4 with a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 324238.4
Subtract 488 from 530 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 10:
420 divided by 122 is 3 with a remainder of 54.
Put 3 as the next digit of the answer. 
Result so far: 324238.43
If we take 366 away from 420, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 11:
If we divide 540 by 122, we get 4 and a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 324238.434
Subtracting 488 from 540 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 12:
520 divided by 122 is 4 with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 324238.4344
If we subtract 488 from 520, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 324238.4344 and a remainder of 0.00032.
