20247839 divided by 120 
We want to figure out the number of times 20247839 can be divided by 120.

Advancing to step 1:
120 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 120

Advancing to step 2:
120 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Take the next digit (2) from the dividend and append it to 20, then repeat: 202 / 120

Moving on to step 3:
The number 120 fits into 202 1 times, leaving a remainder of 82.
The next digit of our result is 1. 
Result so far: 1.0
If we take 120 away from 202, we end up with 82.
Bring next digit (4) of the dividend behind the 82 and repeat the process: 824 / 120

Moving on to step 4:
The number 120 fits into 824 6 times, leaving a remainder of 104.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we take 720 away from 824, we end up with 104.
Grab the next digit (7) from the dividend, add it to 104, then carry on: 1047 / 120

Let's proceed to step 5:
The number 120 fits into 1047 8 times, leaving a remainder of 87.
Record the quotient 8 as the next digit in the result. 
Result so far: 168.0
Deduct 960 from 1047 and we're left with 87.
Grab the next digit (8) from the dividend, add it to 87, then carry on: 878 / 120

On to step 6:
120 goes into 878 7 times with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 1687.0
Subtract 840 from 878 to get 38.
Grab the next digit (3) from the dividend, add it to 38, then carry on: 383 / 120

Step 7:
383 divided by 120 is 3 with a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 16873.0
Deduct 360 from 383 and we're left with 23.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 120

On to step 8:
The number 120 fits into 239 1 times, leaving a remainder of 119.
Use 1 as the next digit of our solution. 
Result so far: 168731.0
The remainder is 119 after subtracting 120 from 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Going ahead to step 9:
The number 120 fits into 1190 9 times, leaving a remainder of 110.
The number 9 becomes the next digit in our result. 
Result so far: 168731.9
If we subtract 1080 from 1190, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 10:
If we divide 1100 by 120, we get 9 and a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 168731.99
If we take 1080 away from 1100, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 168731.99 with a remainder of 0.02.
