We're dividing 20988108 by 78 
We want to divide 20988108 by 78.

Moving on to step 1:
When dividing 2 by 78, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 78

Step 2:
If we divide 20 by 78, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 78

On to step 3:
When dividing 209 by 78, we get 2 with a remainder of 53.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 156 from 209, we get 53.
Fetch the next digit (8) from the dividend, attach it to 53 and continue: 538 / 78

Step 4:
78 goes into 538 6 times with a remainder of 70.
Write down 6 as next digit of the result. 
Result so far: 26.0
The remainder is 70 after subtracting 468 from 538.
Take the next digit (8) from the dividend and append it to 70, then repeat: 708 / 78

Advancing to step 5:
78 can be fit into 708 9 times, resulting in a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 269.0
If we take 702 away from 708, we end up with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 78

On to step 6:
78 goes into 61 0 times with a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 2690.0
If we subtract 0 from 61, we get 61.
Grab the next digit (0) from the dividend, add it to 61, then carry on: 610 / 78

On to step 7:
If we divide 610 by 78, we get 7 and a remainder of 64.
Put 7 as the next digit of the answer. 
Result so far: 26907.0
If we take 546 away from 610, we end up with 64.
Fetch the next digit (8) from the dividend, attach it to 64 and continue: 648 / 78

Going ahead to step 8:
The number 78 fits into 648 8 times, leaving a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 269078.0
If we take 624 away from 648, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
240 divided by 78 is 3 with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 269078.3
The remainder is 6 after subtracting 234 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
The number 78 fits into 60 0 times, leaving a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 269078.3
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
If we divide 600 by 78, we get 7 and a remainder of 54.
Write down 7 as next digit of the result. 
Result so far: 269078.307
If we take 546 away from 600, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 12:
When dividing 540 by 78, we get 6 with a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 269078.3076
Subtracting 468 from 540 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 13:
The number 78 fits into 720 9 times, leaving a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 269078.30769
Subtracting 702 from 720 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 14:
180 divided by 78 is 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 269078.307692
Deduct 156 from 180 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 15:
When dividing 240 by 78, we get 3 with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 269078.3076923
If we take 234 away from 240, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 16:
78 goes into 60 0 times with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 269078.3076923
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 269078.3076923, and the remainder is 6e-08.
