We're dividing 77231899 by 28 
Let's see how many times 28 fits into 77231899.

On to step 1:
When dividing 7 by 28, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 28

Advancing to step 2:
28 goes into 77 2 times with a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 21 after subtracting 56 from 77.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 28

Step 3:
When dividing 212 by 28, we get 7 with a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Subtracting 196 from 212 leaves us with 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 28

Let's proceed to step 4:
The number 28 fits into 163 5 times, leaving a remainder of 23.
The next digit of our result is 5. 
Result so far: 275.0
The remainder is 23 after subtracting 140 from 163.
Grab the next digit (1) from the dividend, add it to 23, then carry on: 231 / 28

Let's proceed to step 5:
231 divided by 28 is 8 with a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 2758.0
If we take 224 away from 231, we end up with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 28

Going ahead to step 6:
If we divide 78 by 28, we get 2 and a remainder of 22.
The next digit of our result is 2. 
Result so far: 27582.0
If we take 56 away from 78, we end up with 22.
Fetch the next digit (9) from the dividend, attach it to 22 and continue: 229 / 28

Moving on to step 7:
28 goes into 229 8 times with a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 275828.0
If we subtract 224 from 229, we get 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 28

Let's proceed to step 8:
59 divided by 28 is 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 2758282.0
Subtract 56 from 59 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
28 can be fit into 30 1 times, resulting in a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 2758282.1
Subtract 28 from 30 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
28 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 2758282.1
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
When dividing 200 by 28, we get 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 2758282.107
If we take 196 away from 200, we end up 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:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 2758282.1071
Subtract 28 from 40 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 13:
The number 28 fits into 120 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 2758282.10714
Deduct 112 from 120 and we're left 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.

Moving on to step 14:
28 goes into 80 2 times with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 2758282.107142
Subtracting 56 from 80 leaves us 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.

Going ahead to step 15:
When dividing 240 by 28, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 2758282.1071428
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.

Going ahead to step 16:
If we divide 160 by 28, we get 5 and a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 2758282.10714285
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.

In conclusion, the division gives 2758282.10714285 with a balance of 2e-08.
