Let's divide 20379044 by 478
Our goal is to divide 20379044 by 478.

Going ahead to step 1:
If we divide 2 by 478, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 478

On to step 2:
When dividing 20 by 478, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 478

Let's proceed to step 3:
478 goes into 203 0 times with a remainder of 203.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 203 and we're left with 203.
Append the next digit (7) from the dividend to 203 and continue with: 2037 / 478

Step 4:
2037 divided by 478 is 4 with a remainder of 125.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 1912 from 2037 and we're left with 125.
Include the next digit (9) from the dividend after 125, then repeat: 1259 / 478

Advancing to step 5:
478 goes into 1259 2 times with a remainder of 303.
Put 2 as the next digit of the answer. 
Result so far: 42.0
If we subtract 956 from 1259, we get 303.
Include the next digit (0) from the dividend after 303, then repeat: 3030 / 478

Going ahead to step 6:
478 can be fit into 3030 6 times, resulting in a remainder of 162.
The next digit of our result is 6. 
Result so far: 426.0
Subtract 2868 from 3030 to get 162.
Take the next digit (4) from the dividend and append it to 162, then repeat: 1624 / 478

Going ahead to step 7:
When dividing 1624 by 478, we get 3 with a remainder of 190.
Use 3 as the next digit of our solution. 
Result so far: 4263.0
Subtracting 1434 from 1624 leaves us with 190.
Bring next digit (4) of the dividend behind the 190 and repeat the process: 1904 / 478

On to step 8:
1904 divided by 478 is 3 with a remainder of 470.
The next digit of our result is 3. 
Result so far: 42633.0
If we subtract 1434 from 1904, we 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.

Step 9:
If we divide 4700 by 478, we get 9 and a remainder of 398.
Use 9 as the next digit of our solution. 
Result so far: 42633.9
The remainder is 398 after subtracting 4302 from 4700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Advancing to step 10:
When dividing 3980 by 478, we get 8 with a remainder of 156.
Record the quotient 8 as the next digit in the result. 
Result so far: 42633.98
Deduct 3824 from 3980 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 11:
478 goes into 1560 3 times with a remainder of 126.
The next digit of our result is 3. 
Result so far: 42633.983
The remainder is 126 after subtracting 1434 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 12:
If we divide 1260 by 478, we get 2 and a remainder of 304.
Write down 2 as next digit of the result. 
Result so far: 42633.9832
If we take 956 away from 1260, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 13:
When dividing 3040 by 478, we get 6 with a remainder of 172.
The number 6 becomes the next digit in our result. 
Result so far: 42633.98326
The remainder is 172 after subtracting 2868 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 14:
1720 divided by 478 is 3 with a remainder of 286.
Use 3 as the next digit of our solution. 
Result so far: 42633.983263
Subtracting 1434 from 1720 leaves us with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

On to step 15:
2860 divided by 478 is 5 with a remainder of 470.
The number 5 becomes the next digit in our result. 
Result so far: 42633.9832635
Deduct 2390 from 2860 and we're left with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Let's proceed to step 16:
When dividing 4700 by 478, we get 9 with a remainder of 398.
The next digit of our result is 9. 
Result so far: 42633.98326359
Subtract 4302 from 4700 to get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Our division results in 42633.98326359 with a remaining 3.98e-07.
