We're dividing 21492850 by 120 
Let's see how many times 120 fits into 21492850.

On to step 1:
2 divided by 120 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 120

On to step 2:
120 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Grab the next digit (4) from the dividend, add it to 21, then carry on: 214 / 120

Moving on to step 3:
The number 120 fits into 214 1 times, leaving a remainder of 94.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 94 after subtracting 120 from 214.
Include the next digit (9) from the dividend after 94, then repeat: 949 / 120

Moving on to step 4:
When dividing 949 by 120, we get 7 with a remainder of 109.
The next digit of our result is 7. 
Result so far: 17.0
If we take 840 away from 949, we end up with 109.
Take the next digit (2) from the dividend and append it to 109, then repeat: 1092 / 120

Advancing to step 5:
120 can be fit into 1092 9 times, resulting in a remainder of 12.
The next digit of our result is 9. 
Result so far: 179.0
Subtracting 1080 from 1092 leaves us with 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 120

Going ahead to step 6:
When dividing 128 by 120, we get 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1791.0
The remainder is 8 after subtracting 120 from 128.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 120

Step 7:
The number 120 fits into 85 0 times, leaving a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 17910.0
If we take 0 away from 85, we end up with 85.
Take the next digit (0) from the dividend and append it to 85, then repeat: 850 / 120

Let's proceed to step 8:
850 divided by 120 is 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 179107.0
The remainder is 10 after subtracting 840 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
120 goes into 100 0 times with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 179107.0
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 10:
120 goes into 1000 8 times with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 179107.08
If we subtract 960 from 1000, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
When dividing 400 by 120, we get 3 with a remainder of 40.
Write down 3 as next digit of the result. 
Result so far: 179107.083
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
The number 120 fits into 400 3 times, leaving a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 179107.0833
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 179107.0833, and the remainder is 0.0004.
