We look at the division of 17783071 by 120 
Let's see how many times 120 fits into 17783071.

Step 1:
When dividing 1 by 120, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 120

Going ahead to step 2:
17 divided by 120 is 0 with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Bring next digit (7) of the dividend behind the 17 and repeat the process: 177 / 120

Going ahead to step 3:
If we divide 177 by 120, we get 1 and a remainder of 57.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 57 after subtracting 120 from 177.
Append the next digit (8) from the dividend to 57 and continue with: 578 / 120

On to step 4:
120 can be fit into 578 4 times, resulting in a remainder of 98.
The next digit of our result is 4. 
Result so far: 14.0
If we take 480 away from 578, we end up with 98.
Bring next digit (3) of the dividend behind the 98 and repeat the process: 983 / 120

Going ahead to step 5:
983 divided by 120 is 8 with a remainder of 23.
Put 8 as the next digit of the answer. 
Result so far: 148.0
If we take 960 away from 983, we end up with 23.
Fetch the next digit (0) from the dividend, attach it to 23 and continue: 230 / 120

On to step 6:
When dividing 230 by 120, we get 1 with a remainder of 110.
The number 1 becomes the next digit in our result. 
Result so far: 1481.0
Subtracting 120 from 230 leaves us with 110.
Grab the next digit (7) from the dividend, add it to 110, then carry on: 1107 / 120

Let's proceed to step 7:
120 goes into 1107 9 times with a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 14819.0
If we take 1080 away from 1107, we end up with 27.
Append the next digit (1) from the dividend to 27 and continue with: 271 / 120

On to step 8:
271 divided by 120 is 2 with a remainder of 31.
Use 2 as the next digit of our solution. 
Result so far: 148192.0
If we subtract 240 from 271, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 9:
When dividing 310 by 120, we get 2 with a remainder of 70.
The number 2 becomes the next digit in our result. 
Result so far: 148192.2
If we subtract 240 from 310, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 10:
When dividing 700 by 120, we get 5 with a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 148192.25
Subtracting 600 from 700 leaves us 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.

Advancing to step 11:
1000 divided by 120 is 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 148192.258
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.

Going ahead to step 12:
When dividing 400 by 120, we get 3 with a remainder of 40.
The next digit of our result is 3. 
Result so far: 148192.2583
If we take 360 away from 400, we end up 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 13:
The number 120 fits into 400 3 times, leaving a remainder of 40.
The next digit of our result is 3. 
Result so far: 148192.25833
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.

After the division, we end up with 148192.25833 and a remainder of 4e-05.
