We look at the division of 20934138 by 789 
We want to figure out the number of times 20934138 can be divided by 789.

Advancing to step 1:
2 divided by 789 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 789

Advancing to step 2:
789 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 789

Going ahead to step 3:
The number 789 fits into 209 0 times, leaving a remainder of 209.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 209 and we're left with 209.
Grab the next digit (3) from the dividend, add it to 209, then carry on: 2093 / 789

Step 4:
If we divide 2093 by 789, we get 2 and a remainder of 515.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1578 from 2093 and we're left with 515.
Bring next digit (4) of the dividend behind the 515 and repeat the process: 5154 / 789

Advancing to step 5:
789 can be fit into 5154 6 times, resulting in a remainder of 420.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
Subtract 4734 from 5154 to get 420.
Include the next digit (1) from the dividend after 420, then repeat: 4201 / 789

On to step 6:
If we divide 4201 by 789, we get 5 and a remainder of 256.
Use 5 as the next digit of our solution. 
Result so far: 265.0
Subtracting 3945 from 4201 leaves us with 256.
Append the next digit (3) from the dividend to 256 and continue with: 2563 / 789

Moving on to step 7:
If we divide 2563 by 789, we get 3 and a remainder of 196.
Write down 3 as next digit of the result. 
Result so far: 2653.0
If we subtract 2367 from 2563, we get 196.
Bring next digit (8) of the dividend behind the 196 and repeat the process: 1968 / 789

Moving on to step 8:
The number 789 fits into 1968 2 times, leaving a remainder of 390.
Use 2 as the next digit of our solution. 
Result so far: 26532.0
Subtracting 1578 from 1968 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Going ahead to step 9:
When dividing 3900 by 789, we get 4 with a remainder of 744.
Put 4 as the next digit of the answer. 
Result so far: 26532.4
If we take 3156 away from 3900, we end up with 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Going ahead to step 10:
789 can be fit into 7440 9 times, resulting in a remainder of 339.
Record the quotient 9 as the next digit in the result. 
Result so far: 26532.49
If we subtract 7101 from 7440, we get 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Moving on to step 11:
The number 789 fits into 3390 4 times, leaving a remainder of 234.
Put 4 as the next digit of the answer. 
Result so far: 26532.494
Subtracting 3156 from 3390 leaves us with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Advancing to step 12:
789 can be fit into 2340 2 times, resulting in a remainder of 762.
The next digit of our result is 2. 
Result so far: 26532.4942
Subtract 1578 from 2340 to get 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

Going ahead to step 13:
789 can be fit into 7620 9 times, resulting in a remainder of 519.
The number 9 becomes the next digit in our result. 
Result so far: 26532.49429
Subtract 7101 from 7620 to get 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Advancing to step 14:
789 can be fit into 5190 6 times, resulting in a remainder of 456.
The next digit of our result is 6. 
Result so far: 26532.494296
If we subtract 4734 from 5190, we get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Let's proceed to step 15:
4560 divided by 789 is 5 with a remainder of 615.
The number 5 becomes the next digit in our result. 
Result so far: 26532.4942965
Deduct 3945 from 4560 and we're left with 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Moving on to step 16:
789 can be fit into 6150 7 times, resulting in a remainder of 627.
Write down 7 as next digit of the result. 
Result so far: 26532.49429657
Subtracting 5523 from 6150 leaves us with 627.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6270, and continue the process.

The final result is 26532.49429657 with a remainder of 6.27e-07.
