We look at the division of 12337 by 78 
We want to figure out the number of times 12337 can be divided by 78.

Moving on to step 1:
The number 78 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 78

On to step 2:
12 divided by 78 is 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 78

Going ahead to step 3:
When dividing 123 by 78, we get 1 with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 78 from 123 and we're left with 45.
Include the next digit (3) from the dividend after 45, then repeat: 453 / 78

Going ahead to step 4:
78 goes into 453 5 times with a remainder of 63.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 390 from 453 and we're left with 63.
Bring next digit (7) of the dividend behind the 63 and repeat the process: 637 / 78

Advancing to step 5:
If we divide 637 by 78, we get 8 and a remainder of 13.
Put 8 as the next digit of the answer. 
Result so far: 158.0
Subtracting 624 from 637 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 6:
130 divided by 78 is 1 with a remainder of 52.
The next digit of our result is 1. 
Result so far: 158.1
If we take 78 away from 130, 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.

Moving on to step 7:
If we divide 520 by 78, we get 6 and a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 158.16
Deduct 468 from 520 and we're left 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.

Going ahead to step 8:
520 divided by 78 is 6 with a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 158.166
The remainder is 52 after subtracting 468 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Our division results in 158.166 with a remaining 0.0052.
