We look at the division of 11348330 by 420 
Let's see how many times 420 fits into 11348330.

Step 1:
420 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 420

On to step 2:
If we divide 11 by 420, we get 0 and a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 11, we end up with 11.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 420

Advancing to step 3:
If we divide 113 by 420, we get 0 and a remainder of 113.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 113, we get 113.
Include the next digit (4) from the dividend after 113, then repeat: 1134 / 420

Going ahead to step 4:
If we divide 1134 by 420, we get 2 and a remainder of 294.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 840 from 1134, we get 294.
Append the next digit (8) from the dividend to 294 and continue with: 2948 / 420

Step 5:
2948 divided by 420 is 7 with a remainder of 8.
The next digit of our result is 7. 
Result so far: 27.0
Subtracting 2940 from 2948 leaves us with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 420

Going ahead to step 6:
83 divided by 420 is 0 with a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 270.0
Subtracting 0 from 83 leaves us with 83.
Include the next digit (3) from the dividend after 83, then repeat: 833 / 420

Advancing to step 7:
420 goes into 833 1 times with a remainder of 413.
The number 1 becomes the next digit in our result. 
Result so far: 2701.0
Subtracting 420 from 833 leaves us with 413.
Fetch the next digit (0) from the dividend, attach it to 413 and continue: 4130 / 420

On to step 8:
The number 420 fits into 4130 9 times, leaving a remainder of 350.
Use 9 as the next digit of our solution. 
Result so far: 27019.0
Subtract 3780 from 4130 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 9:
420 can be fit into 3500 8 times, resulting in a remainder of 140.
Write down 8 as next digit of the result. 
Result so far: 27019.8
Subtract 3360 from 3500 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 10:
The number 420 fits into 1400 3 times, leaving a remainder of 140.
The next digit of our result is 3. 
Result so far: 27019.83
If we take 1260 away from 1400, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 11:
1400 divided by 420 is 3 with a remainder of 140.
The next digit of our result is 3. 
Result so far: 27019.833
Subtracting 1260 from 1400 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The final outcome is 27019.833, with a leftover of 0.014.
