764991 ÷ 28 
We want to figure out the number of times 764991 can be divided by 28.

On to step 1:
28 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 28

Moving on to step 2:
The number 28 fits into 76 2 times, leaving a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 56 from 76 to get 20.
Grab the next digit (4) from the dividend, add it to 20, then carry on: 204 / 28

On to step 3:
28 goes into 204 7 times with a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
If we take 196 away from 204, we end up with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 28

Advancing to step 4:
The number 28 fits into 89 3 times, leaving a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 273.0
Subtracting 84 from 89 leaves us with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 28

Let's proceed to step 5:
If we divide 59 by 28, we get 2 and a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 2732.0
If we subtract 56 from 59, we get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 28

Let's proceed to step 6:
The number 28 fits into 31 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 27321.0
Subtract 28 from 31 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.

Let's proceed to step 7:
30 divided by 28 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 27321.1
Subtracting 28 from 30 leaves us 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.

Moving on to step 8:
28 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 27321.1
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.

Moving on to step 9:
200 divided by 28 is 7 with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 27321.107
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.

Let's proceed to step 10:
When dividing 40 by 28, we get 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 27321.1071
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.

On to step 11:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 27321.10714
Subtract 112 from 120 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
When dividing 80 by 28, we get 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 27321.107142
If we take 56 away from 80, 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.

On to step 13:
28 goes into 240 8 times with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 27321.1071428
Subtract 224 from 240 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 14:
160 divided by 28 is 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 27321.10714285
If we take 140 away from 160, 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.

The final outcome is 27321.10714285, with a leftover of 2e-08.
