Let's divide 21068349 by 789
We want to figure out the number of times 21068349 can be divided by 789.

Advancing to step 1:
2 divided by 789 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 789

Moving on to step 2:
If we divide 21 by 789, we get 0 and 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.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 789

Moving on to step 3:
789 goes into 210 0 times with a remainder of 210.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 210 to get 210.
Bring next digit (6) of the dividend behind the 210 and repeat the process: 2106 / 789

Going ahead to step 4:
789 goes into 2106 2 times with a remainder of 528.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 528 after subtracting 1578 from 2106.
Take the next digit (8) from the dividend and append it to 528, then repeat: 5288 / 789

Going ahead to step 5:
The number 789 fits into 5288 6 times, leaving a remainder of 554.
Use 6 as the next digit of our solution. 
Result so far: 26.0
Subtracting 4734 from 5288 leaves us with 554.
Fetch the next digit (3) from the dividend, attach it to 554 and continue: 5543 / 789

On to step 6:
If we divide 5543 by 789, we get 7 and a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 267.0
The remainder is 20 after subtracting 5523 from 5543.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 789

Going ahead to step 7:
When dividing 204 by 789, we get 0 with a remainder of 204.
Put 0 as the next digit of the answer. 
Result so far: 2670.0
If we take 0 away from 204, we end up with 204.
Fetch the next digit (9) from the dividend, attach it to 204 and continue: 2049 / 789

On to step 8:
2049 divided by 789 is 2 with a remainder of 471.
Use 2 as the next digit of our solution. 
Result so far: 26702.0
If we subtract 1578 from 2049, we get 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

On to step 9:
When dividing 4710 by 789, we get 5 with a remainder of 765.
Record the quotient 5 as the next digit in the result. 
Result so far: 26702.5
If we take 3945 away from 4710, we end up with 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

Let's proceed to step 10:
If we divide 7650 by 789, we get 9 and a remainder of 549.
Use 9 as the next digit of our solution. 
Result so far: 26702.59
If we subtract 7101 from 7650, we get 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Advancing to step 11:
If we divide 5490 by 789, we get 6 and a remainder of 756.
Put 6 as the next digit of the answer. 
Result so far: 26702.596
Subtract 4734 from 5490 to get 756.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7560, and continue the process.

Step 12:
789 goes into 7560 9 times with a remainder of 459.
The next digit of our result is 9. 
Result so far: 26702.5969
The remainder is 459 after subtracting 7101 from 7560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Step 13:
If we divide 4590 by 789, we get 5 and a remainder of 645.
The number 5 becomes the next digit in our result. 
Result so far: 26702.59695
Deduct 3945 from 4590 and we're left with 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

Going ahead to step 14:
789 goes into 6450 8 times with a remainder of 138.
The number 8 becomes the next digit in our result. 
Result so far: 26702.596958
Subtract 6312 from 6450 to get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Moving on to step 15:
The number 789 fits into 1380 1 times, leaving a remainder of 591.
The number 1 becomes the next digit in our result. 
Result so far: 26702.5969581
The remainder is 591 after subtracting 789 from 1380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

On to step 16:
789 goes into 5910 7 times with a remainder of 387.
The number 7 becomes the next digit in our result. 
Result so far: 26702.59695817
If we take 5523 away from 5910, we end up with 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

The final outcome is 26702.59695817, with a leftover of 3.87e-07.
