Let's divide 21377197 by 28
We want to divide 21377197 by 28.

Advancing to step 1:
The number 28 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 28

Moving on to step 2:
28 can be fit into 21 0 times, resulting in a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 28

Advancing to step 3:
28 can be fit into 213 7 times, resulting in a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 196 away from 213, we end up with 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 28

Going ahead to step 4:
If we divide 177 by 28, we get 6 and a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
Deduct 168 from 177 and we're left with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 28

Let's proceed to step 5:
97 divided by 28 is 3 with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 763.0
If we subtract 84 from 97, we get 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 28

Step 6:
28 goes into 131 4 times with a remainder of 19.
Put 4 as the next digit of the answer. 
Result so far: 7634.0
Deduct 112 from 131 and we're left with 19.
Include the next digit (9) from the dividend after 19, then repeat: 199 / 28

Advancing to step 7:
199 divided by 28 is 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 76347.0
If we subtract 196 from 199, we get 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 28

Let's proceed to step 8:
28 goes into 37 1 times with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 763471.0
Subtract 28 from 37 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
The number 28 fits into 90 3 times, leaving a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 763471.3
Deduct 84 from 90 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
28 goes into 60 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 763471.32
Deduct 56 from 60 and we're left 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.

Advancing to step 11:
If we divide 40 by 28, we get 1 and a remainder of 12.
The next digit of our result is 1. 
Result so far: 763471.321
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.

Going ahead to step 12:
28 goes into 120 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 763471.3214
If we subtract 112 from 120, we 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 13:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 763471.32142
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.

Moving on to step 14:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 763471.321428
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.

Moving on to step 15:
160 divided by 28 is 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 763471.3214285
If we subtract 140 from 160, we 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.

On to step 16:
If we divide 200 by 28, we get 7 and a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 763471.32142857
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.

In conclusion, the division gives 763471.32142857 with a balance of 4e-09.
