Let's divide 870621 by 28
We're looking to find how many times 28 goes into 870621.

Let's proceed to step 1:
28 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 28

On to step 2:
28 can be fit into 87 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 84 from 87 and we're left with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 28

Moving on to step 3:
30 divided by 28 is 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtracting 28 from 30 leaves us with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 28

Let's proceed to step 4:
When dividing 26 by 28, we get 0 with a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 310.0
The remainder is 26 after subtracting 0 from 26.
Grab the next digit (2) from the dividend, add it to 26, then carry on: 262 / 28

Moving on to step 5:
If we divide 262 by 28, we get 9 and a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 3109.0
Deduct 252 from 262 and we're left with 10.
Fetch the next digit (1) from the dividend, attach it to 10 and continue: 101 / 28

Advancing to step 6:
The number 28 fits into 101 3 times, leaving a remainder of 17.
The next digit of our result is 3. 
Result so far: 31093.0
Subtracting 84 from 101 leaves us 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 7:
28 goes into 170 6 times with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 31093.6
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
20 divided by 28 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 31093.6
Subtract 0 from 20 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.

Let's proceed to step 9:
28 can be fit into 200 7 times, resulting in a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 31093.607
If we subtract 196 from 200, 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.

Step 10:
28 goes into 40 1 times with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 31093.6071
The remainder is 12 after subtracting 28 from 40.
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 11:
The number 28 fits into 120 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 31093.60714
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.

Going ahead to step 12:
When dividing 80 by 28, we get 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 31093.607142
The remainder is 24 after subtracting 56 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
If we divide 240 by 28, we get 8 and a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 31093.6071428
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.

Going ahead to step 14:
If we divide 160 by 28, we get 5 and a remainder of 20.
The next digit of our result is 5. 
Result so far: 31093.60714285
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.

In conclusion, the division gives 31093.60714285 with a balance of 2e-08.
