We look at the division of 20406510 by 481 
We're looking to find how many times 481 goes into 20406510.

Let's proceed to step 1:
2 divided by 481 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 481

Going ahead to step 2:
The number 481 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 subtract 0 from 20, we get 20.
Grab the next digit (4) from the dividend, add it to 20, then carry on: 204 / 481

Advancing to step 3:
When dividing 204 by 481, we get 0 with a remainder of 204.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 204, we end up with 204.
Fetch the next digit (0) from the dividend, attach it to 204 and continue: 2040 / 481

Let's proceed to step 4:
When dividing 2040 by 481, we get 4 with a remainder of 116.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 1924 from 2040 to get 116.
Include the next digit (6) from the dividend after 116, then repeat: 1166 / 481

Going ahead to step 5:
If we divide 1166 by 481, we get 2 and a remainder of 204.
Write down 2 as next digit of the result. 
Result so far: 42.0
Subtract 962 from 1166 to get 204.
Include the next digit (5) from the dividend after 204, then repeat: 2045 / 481

Step 6:
The number 481 fits into 2045 4 times, leaving a remainder of 121.
The number 4 becomes the next digit in our result. 
Result so far: 424.0
The remainder is 121 after subtracting 1924 from 2045.
Append the next digit (1) from the dividend to 121 and continue with: 1211 / 481

Step 7:
The number 481 fits into 1211 2 times, leaving a remainder of 249.
Use 2 as the next digit of our solution. 
Result so far: 4242.0
Subtracting 962 from 1211 leaves us with 249.
Fetch the next digit (0) from the dividend, attach it to 249 and continue: 2490 / 481

Moving on to step 8:
The number 481 fits into 2490 5 times, leaving a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 42425.0
If we take 2405 away from 2490, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 9:
The number 481 fits into 850 1 times, leaving a remainder of 369.
Write down 1 as next digit of the result. 
Result so far: 42425.1
The remainder is 369 after subtracting 481 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Step 10:
The number 481 fits into 3690 7 times, leaving a remainder of 323.
Record the quotient 7 as the next digit in the result. 
Result so far: 42425.17
If we take 3367 away from 3690, we end up with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Moving on to step 11:
481 goes into 3230 6 times with a remainder of 344.
Use 6 as the next digit of our solution. 
Result so far: 42425.176
Subtracting 2886 from 3230 leaves us with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Advancing to step 12:
When dividing 3440 by 481, we get 7 with a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 42425.1767
Deduct 3367 from 3440 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 13:
The number 481 fits into 730 1 times, leaving a remainder of 249.
Record the quotient 1 as the next digit in the result. 
Result so far: 42425.17671
If we subtract 481 from 730, we get 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Step 14:
When dividing 2490 by 481, we get 5 with a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 42425.176715
Subtract 2405 from 2490 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 15:
The number 481 fits into 850 1 times, leaving a remainder of 369.
The number 1 becomes the next digit in our result. 
Result so far: 42425.1767151
The remainder is 369 after subtracting 481 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Advancing to step 16:
The number 481 fits into 3690 7 times, leaving a remainder of 323.
Put 7 as the next digit of the answer. 
Result so far: 42425.17671517
If we take 3367 away from 3690, we end up with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

In conclusion, the division gives 42425.17671517 with a balance of 3.23e-07.
