615901 divided by 28 
We want to figure out the number of times 615901 can be divided by 28.

Moving on to step 1:
The number 28 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 28

On to step 2:
28 can be fit into 61 2 times, resulting in a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 56 away from 61, we end up with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 28

On to step 3:
28 goes into 55 1 times with a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we take 28 away from 55, we end up with 27.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 28

Going ahead to step 4:
The number 28 fits into 279 9 times, leaving a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 219.0
The remainder is 27 after subtracting 252 from 279.
Append the next digit (0) from the dividend to 27 and continue with: 270 / 28

Going ahead to step 5:
The number 28 fits into 270 9 times, leaving a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 2199.0
The remainder is 18 after subtracting 252 from 270.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 28

On to step 6:
The number 28 fits into 181 6 times, leaving a remainder of 13.
Put 6 as the next digit of the answer. 
Result so far: 21996.0
The remainder is 13 after subtracting 168 from 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
28 goes into 130 4 times with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 21996.4
Deduct 112 from 130 and we're left 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.

Moving on to step 8:
180 divided by 28 is 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 21996.46
If we take 168 away from 180, we end up 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.

Let's proceed to step 9:
When dividing 120 by 28, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 21996.464
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.

Step 10:
28 can be fit into 80 2 times, resulting in a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 21996.4642
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.

Step 11:
When dividing 240 by 28, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 21996.46428
If we subtract 224 from 240, we 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.

On to step 12:
160 divided by 28 is 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 21996.464285
Deduct 140 from 160 and we're left 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.

On to step 13:
When dividing 200 by 28, we get 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 21996.4642857
Subtract 196 from 200 to 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.

Advancing to step 14:
The number 28 fits into 40 1 times, leaving a remainder of 12.
The next digit of our result is 1. 
Result so far: 21996.46428571
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.

After the division, we end up with 21996.46428571 and a remainder of 1.2e-08.
