Let's divide 118520 by 78
We want to divide 118520 by 78.

Going ahead to step 1:
1 divided by 78 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 78

Step 2:
78 can be fit into 11 0 times, resulting in a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 11, we get 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 78

Let's proceed to step 3:
78 can be fit into 118 1 times, resulting in a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 78 from 118 leaves us with 40.
Include the next digit (5) from the dividend after 40, then repeat: 405 / 78

Advancing to step 4:
78 can be fit into 405 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 390 from 405 and we're left with 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 78

Moving on to step 5:
78 goes into 152 1 times with a remainder of 74.
Use 1 as the next digit of our solution. 
Result so far: 151.0
Subtract 78 from 152 to get 74.
Fetch the next digit (0) from the dividend, attach it to 74 and continue: 740 / 78

Going ahead to step 6:
When dividing 740 by 78, we get 9 with a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 1519.0
The remainder is 38 after subtracting 702 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 7:
78 goes into 380 4 times with a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 1519.4
Subtracting 312 from 380 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 8:
The number 78 fits into 680 8 times, leaving a remainder of 56.
The next digit of our result is 8. 
Result so far: 1519.48
Subtracting 624 from 680 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 9:
78 goes into 560 7 times with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 1519.487
If we take 546 away from 560, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
78 goes into 140 1 times with a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 1519.4871
If we subtract 78 from 140, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 11:
When dividing 620 by 78, we get 7 with a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 1519.48717
Deduct 546 from 620 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 12:
78 can be fit into 740 9 times, resulting in a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 1519.487179
Subtract 702 from 740 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 13:
If we divide 380 by 78, we get 4 and a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 1519.4871794
Subtracting 312 from 380 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 14:
78 goes into 680 8 times with a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 1519.48717948
Subtract 624 from 680 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Our division results in 1519.48717948 with a remaining 5.6e-08.
