Let's divide 78100249 by 28
We want to divide 78100249 by 28.

Let's proceed to step 1:
If we divide 7 by 28, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 28

On to step 2:
28 can be fit into 78 2 times, resulting in a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 56 from 78 leaves us with 22.
Append the next digit (1) from the dividend to 22 and continue with: 221 / 28

Step 3:
When dividing 221 by 28, we get 7 with a remainder of 25.
Write down 7 as next digit of the result. 
Result so far: 27.0
Deduct 196 from 221 and we're left with 25.
Append the next digit (0) from the dividend to 25 and continue with: 250 / 28

Advancing to step 4:
28 can be fit into 250 8 times, resulting in a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 278.0
If we take 224 away from 250, we end up with 26.
Grab the next digit (0) from the dividend, add it to 26, then carry on: 260 / 28

Going ahead to step 5:
When dividing 260 by 28, we get 9 with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 2789.0
The remainder is 8 after subtracting 252 from 260.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 28

On to step 6:
If we divide 82 by 28, we get 2 and a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 27892.0
If we take 56 away from 82, we end up with 26.
Bring next digit (4) of the dividend behind the 26 and repeat the process: 264 / 28

Step 7:
The number 28 fits into 264 9 times, leaving a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 278929.0
If we subtract 252 from 264, we get 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 28

Advancing to step 8:
129 divided by 28 is 4 with a remainder of 17.
Write down 4 as next digit of the result. 
Result so far: 2789294.0
Deduct 112 from 129 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 9:
When dividing 170 by 28, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 2789294.6
Deduct 168 from 170 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
The number 28 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 2789294.6
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
28 goes into 200 7 times with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 2789294.607
Deduct 196 from 200 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
When dividing 40 by 28, we get 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 2789294.6071
Deduct 28 from 40 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 13:
120 divided by 28 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 2789294.60714
If we take 112 away from 120, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 14:
28 can be fit into 80 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 2789294.607142
Subtract 56 from 80 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 15:
The number 28 fits into 240 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 2789294.6071428
Deduct 224 from 240 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 16:
The number 28 fits into 160 5 times, leaving a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 2789294.60714285
Subtract 140 from 160 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 2789294.60714285 with a remaining 2e-08.
