Let's divide 21069572 by 790
We want to divide 21069572 by 790.

Let's proceed to step 1:
2 divided by 790 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 790

Let's proceed to step 2:
790 goes into 21 0 times with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 790

On to step 3:
If we divide 210 by 790, we get 0 and a remainder of 210.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 210 and we're left with 210.
Grab the next digit (6) from the dividend, add it to 210, then carry on: 2106 / 790

Moving on to step 4:
If we divide 2106 by 790, we get 2 and a remainder of 526.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 1580 away from 2106, we end up with 526.
Take the next digit (9) from the dividend and append it to 526, then repeat: 5269 / 790

On to step 5:
790 goes into 5269 6 times with a remainder of 529.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
Subtracting 4740 from 5269 leaves us with 529.
Take the next digit (5) from the dividend and append it to 529, then repeat: 5295 / 790

Step 6:
When dividing 5295 by 790, we get 6 with a remainder of 555.
Write down 6 as next digit of the result. 
Result so far: 266.0
If we take 4740 away from 5295, we end up with 555.
Include the next digit (7) from the dividend after 555, then repeat: 5557 / 790

Going ahead to step 7:
When dividing 5557 by 790, we get 7 with a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 2667.0
The remainder is 27 after subtracting 5530 from 5557.
Include the next digit (2) from the dividend after 27, then repeat: 272 / 790

Moving on to step 8:
790 can be fit into 272 0 times, resulting in a remainder of 272.
Record the quotient 0 as the next digit in the result. 
Result so far: 26670.0
If we subtract 0 from 272, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 9:
If we divide 2720 by 790, we get 3 and a remainder of 350.
Write down 3 as next digit of the result. 
Result so far: 26670.3
Subtract 2370 from 2720 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 10:
790 can be fit into 3500 4 times, resulting in a remainder of 340.
The number 4 becomes the next digit in our result. 
Result so far: 26670.34
Deduct 3160 from 3500 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 11:
790 can be fit into 3400 4 times, resulting in a remainder of 240.
Record the quotient 4 as the next digit in the result. 
Result so far: 26670.344
Subtracting 3160 from 3400 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final result is 26670.344 with a remainder of 0.024.
