We're dividing 20907791 by 506 
We want to divide 20907791 by 506.

Step 1:
506 goes into 2 0 times 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.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 506

On to step 2:
The number 506 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 506

Going ahead to step 3:
When dividing 209 by 506, we get 0 with a remainder of 209.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 209 leaves us with 209.
Bring next digit (0) of the dividend behind the 209 and repeat the process: 2090 / 506

Let's proceed to step 4:
When dividing 2090 by 506, we get 4 with a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 2024 from 2090 to get 66.
Take the next digit (7) from the dividend and append it to 66, then repeat: 667 / 506

Let's proceed to step 5:
When dividing 667 by 506, we get 1 with a remainder of 161.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
If we take 506 away from 667, we end up with 161.
Bring next digit (7) of the dividend behind the 161 and repeat the process: 1617 / 506

Step 6:
506 can be fit into 1617 3 times, resulting in a remainder of 99.
Record the quotient 3 as the next digit in the result. 
Result so far: 413.0
The remainder is 99 after subtracting 1518 from 1617.
Fetch the next digit (9) from the dividend, attach it to 99 and continue: 999 / 506

Going ahead to step 7:
506 can be fit into 999 1 times, resulting in a remainder of 493.
Use 1 as the next digit of our solution. 
Result so far: 4131.0
Subtracting 506 from 999 leaves us with 493.
Append the next digit (1) from the dividend to 493 and continue with: 4931 / 506

On to step 8:
If we divide 4931 by 506, we get 9 and a remainder of 377.
Use 9 as the next digit of our solution. 
Result so far: 41319.0
The remainder is 377 after subtracting 4554 from 4931.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Let's proceed to step 9:
When dividing 3770 by 506, we get 7 with a remainder of 228.
Record the quotient 7 as the next digit in the result. 
Result so far: 41319.7
If we take 3542 away from 3770, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 10:
506 can be fit into 2280 4 times, resulting in a remainder of 256.
Put 4 as the next digit of the answer. 
Result so far: 41319.74
Deduct 2024 from 2280 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 11:
2560 divided by 506 is 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 41319.745
The remainder is 30 after subtracting 2530 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
506 goes into 300 0 times with a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 41319.745
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 13:
506 can be fit into 3000 5 times, resulting in a remainder of 470.
Put 5 as the next digit of the answer. 
Result so far: 41319.74505
Subtract 2530 from 3000 to get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Advancing to step 14:
506 goes into 4700 9 times with a remainder of 146.
Put 9 as the next digit of the answer. 
Result so far: 41319.745059
Subtract 4554 from 4700 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Advancing to step 15:
506 goes into 1460 2 times with a remainder of 448.
Record the quotient 2 as the next digit in the result. 
Result so far: 41319.7450592
Deduct 1012 from 1460 and we're left with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Going ahead to step 16:
When dividing 4480 by 506, we get 8 with a remainder of 432.
The next digit of our result is 8. 
Result so far: 41319.74505928
If we subtract 4048 from 4480, we get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

In conclusion, the division gives 41319.74505928 with a balance of 4.32e-07.
