76990405 divided by 28 
Our goal is to divide 76990405 by 28.

Moving on to step 1:
When dividing 7 by 28, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 28

Let's proceed to step 2:
When dividing 76 by 28, we get 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 20 after subtracting 56 from 76.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 28

On to step 3:
28 can be fit into 209 7 times, resulting in a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 27.0
If we take 196 away from 209, we end up with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 28

Going ahead to step 4:
The number 28 fits into 139 4 times, leaving a remainder of 27.
Put 4 as the next digit of the answer. 
Result so far: 274.0
The remainder is 27 after subtracting 112 from 139.
Grab the next digit (0) from the dividend, add it to 27, then carry on: 270 / 28

Moving on to step 5:
When dividing 270 by 28, we get 9 with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 2749.0
Deduct 252 from 270 and we're left with 18.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 28

Let's proceed to step 6:
28 goes into 184 6 times with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 27496.0
Subtract 168 from 184 to get 16.
Take the next digit (0) from the dividend and append it to 16, then repeat: 160 / 28

Advancing to step 7:
The number 28 fits into 160 5 times, leaving a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 274965.0
The remainder is 20 after subtracting 140 from 160.
Take the next digit (5) from the dividend and append it to 20, then repeat: 205 / 28

On to step 8:
28 can be fit into 205 7 times, resulting in a remainder of 9.
The next digit of our result is 7. 
Result so far: 2749657.0
If we take 196 away from 205, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
90 divided by 28 is 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 2749657.3
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
28 can be fit into 60 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 2749657.32
If we subtract 56 from 60, we get 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 11:
The number 28 fits into 40 1 times, leaving a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 2749657.321
Subtracting 28 from 40 leaves us 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.

On to step 12:
If we divide 120 by 28, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 2749657.3214
Subtracting 112 from 120 leaves us 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.

Going ahead to step 13:
When dividing 80 by 28, we get 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 2749657.32142
If we subtract 56 from 80, we 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.

Step 14:
The number 28 fits into 240 8 times, leaving a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 2749657.321428
The remainder is 16 after subtracting 224 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 15:
28 can be fit into 160 5 times, resulting in a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 2749657.3214285
Subtracting 140 from 160 leaves us 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.

Moving on to step 16:
200 divided by 28 is 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 2749657.32142857
The remainder is 4 after subtracting 196 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 2749657.32142857 with a balance of 4e-09.
