We're dividing 19038998 by 420 
We want to divide 19038998 by 420.

On to step 1:
1 divided by 420 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 420

On to step 2:
19 divided by 420 is 0 with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Fetch the next digit (0) from the dividend, attach it to 19 and continue: 190 / 420

Step 3:
420 goes into 190 0 times with a remainder of 190.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 190, we end up with 190.
Append the next digit (3) from the dividend to 190 and continue with: 1903 / 420

Advancing to step 4:
If we divide 1903 by 420, we get 4 and a remainder of 223.
The next digit of our result is 4. 
Result so far: 4.0
If we take 1680 away from 1903, we end up with 223.
Take the next digit (8) from the dividend and append it to 223, then repeat: 2238 / 420

On to step 5:
The number 420 fits into 2238 5 times, leaving a remainder of 138.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
If we subtract 2100 from 2238, we get 138.
Take the next digit (9) from the dividend and append it to 138, then repeat: 1389 / 420

Step 6:
When dividing 1389 by 420, we get 3 with a remainder of 129.
Put 3 as the next digit of the answer. 
Result so far: 453.0
Subtracting 1260 from 1389 leaves us with 129.
Grab the next digit (9) from the dividend, add it to 129, then carry on: 1299 / 420

On to step 7:
420 goes into 1299 3 times with a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 4533.0
The remainder is 39 after subtracting 1260 from 1299.
Take the next digit (8) from the dividend and append it to 39, then repeat: 398 / 420

Going ahead to step 8:
If we divide 398 by 420, we get 0 and a remainder of 398.
Record the quotient 0 as the next digit in the result. 
Result so far: 45330.0
Subtract 0 from 398 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.

Going ahead to step 9:
The number 420 fits into 3980 9 times, leaving a remainder of 200.
Write down 9 as next digit of the result. 
Result so far: 45330.9
If we subtract 3780 from 3980, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 10:
420 can be fit into 2000 4 times, resulting in a remainder of 320.
The next digit of our result is 4. 
Result so far: 45330.94
Deduct 1680 from 2000 and we're left 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.

Step 11:
3200 divided by 420 is 7 with a remainder of 260.
The number 7 becomes the next digit in our result. 
Result so far: 45330.947
Subtract 2940 from 3200 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 12:
2600 divided by 420 is 6 with a remainder of 80.
The number 6 becomes the next digit in our result. 
Result so far: 45330.9476
If we subtract 2520 from 2600, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 13:
800 divided by 420 is 1 with a remainder of 380.
Write down 1 as next digit of the result. 
Result so far: 45330.94761
Subtract 420 from 800 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 14:
420 can be fit into 3800 9 times, resulting in a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 45330.947619
If we take 3780 away from 3800, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 15:
200 divided by 420 is 0 with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 45330.947619
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 16:
When dividing 2000 by 420, we get 4 with a remainder of 320.
Put 4 as the next digit of the answer. 
Result so far: 45330.94761904
If we take 1680 away from 2000, we end up 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.

After the division, we end up with 45330.94761904 and a remainder of 3.2e-07.
