We're dividing 16780172 by 122 
Our goal is to divide 16780172 by 122.

Step 1:
122 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 122

Advancing to step 2:
If we divide 16 by 122, we get 0 and a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Take the next digit (7) from the dividend and append it to 16, then repeat: 167 / 122

Step 3:
122 goes into 167 1 times with a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 122 from 167, we get 45.
Bring next digit (8) of the dividend behind the 45 and repeat the process: 458 / 122

Moving on to step 4:
458 divided by 122 is 3 with a remainder of 92.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 366 from 458 and we're left with 92.
Grab the next digit (0) from the dividend, add it to 92, then carry on: 920 / 122

Moving on to step 5:
920 divided by 122 is 7 with a remainder of 66.
The number 7 becomes the next digit in our result. 
Result so far: 137.0
Subtract 854 from 920 to get 66.
Take the next digit (1) from the dividend and append it to 66, then repeat: 661 / 122

Step 6:
122 goes into 661 5 times with a remainder of 51.
The next digit of our result is 5. 
Result so far: 1375.0
Deduct 610 from 661 and we're left with 51.
Fetch the next digit (7) from the dividend, attach it to 51 and continue: 517 / 122

Going ahead to step 7:
517 divided by 122 is 4 with a remainder of 29.
The number 4 becomes the next digit in our result. 
Result so far: 13754.0
If we subtract 488 from 517, we get 29.
Bring next digit (2) of the dividend behind the 29 and repeat the process: 292 / 122

Advancing to step 8:
If we divide 292 by 122, we get 2 and a remainder of 48.
The next digit of our result is 2. 
Result so far: 137542.0
Subtracting 244 from 292 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 9:
480 divided by 122 is 3 with a remainder of 114.
Put 3 as the next digit of the answer. 
Result so far: 137542.3
The remainder is 114 after subtracting 366 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 10:
122 goes into 1140 9 times with a remainder of 42.
Record the quotient 9 as the next digit in the result. 
Result so far: 137542.39
If we take 1098 away from 1140, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 11:
If we divide 420 by 122, we get 3 and a remainder of 54.
The next digit of our result is 3. 
Result so far: 137542.393
Subtract 366 from 420 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 12:
122 goes into 540 4 times with a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 137542.3934
If we take 488 away from 540, we end up 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.

On to step 13:
When dividing 520 by 122, we get 4 with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 137542.39344
The remainder is 32 after subtracting 488 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 137542.39344, and the remainder is 3.2e-05.
