We look at the division of 21752170 by 481 
We're looking to find how many times 481 goes into 21752170.

Moving on to step 1:
When dividing 2 by 481, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 481

On to step 2:
If we divide 21 by 481, we get 0 and a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 481

On to step 3:
481 can be fit into 217 0 times, resulting in a remainder of 217.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 217 leaves us with 217.
Include the next digit (5) from the dividend after 217, then repeat: 2175 / 481

Advancing to step 4:
When dividing 2175 by 481, we get 4 with a remainder of 251.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 251 after subtracting 1924 from 2175.
Take the next digit (2) from the dividend and append it to 251, then repeat: 2512 / 481

Step 5:
481 goes into 2512 5 times with a remainder of 107.
The next digit of our result is 5. 
Result so far: 45.0
Subtract 2405 from 2512 to get 107.
Fetch the next digit (1) from the dividend, attach it to 107 and continue: 1071 / 481

Advancing to step 6:
When dividing 1071 by 481, we get 2 with a remainder of 109.
Put 2 as the next digit of the answer. 
Result so far: 452.0
If we subtract 962 from 1071, we get 109.
Take the next digit (7) from the dividend and append it to 109, then repeat: 1097 / 481

Moving on to step 7:
481 goes into 1097 2 times with a remainder of 135.
Write down 2 as next digit of the result. 
Result so far: 4522.0
Subtract 962 from 1097 to get 135.
Fetch the next digit (0) from the dividend, attach it to 135 and continue: 1350 / 481

Let's proceed to step 8:
481 goes into 1350 2 times with a remainder of 388.
Record the quotient 2 as the next digit in the result. 
Result so far: 45222.0
If we subtract 962 from 1350, we get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

On to step 9:
The number 481 fits into 3880 8 times, leaving a remainder of 32.
The next digit of our result is 8. 
Result so far: 45222.8
Subtract 3848 from 3880 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
481 can be fit into 320 0 times, resulting in a remainder of 320.
The next digit of our result is 0. 
Result so far: 45222.8
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 11:
481 goes into 3200 6 times with a remainder of 314.
Put 6 as the next digit of the answer. 
Result so far: 45222.806
If we subtract 2886 from 3200, we get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Moving on to step 12:
3140 divided by 481 is 6 with a remainder of 254.
The next digit of our result is 6. 
Result so far: 45222.8066
Deduct 2886 from 3140 and we're left with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

The final outcome is 45222.8066, with a leftover of 0.00254.
