We look at the division of 6099596 by 420 
Let's see how many times 420 fits into 6099596.

Let's proceed to step 1:
If we divide 6 by 420, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 420

Step 2:
If we divide 60 by 420, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 60, we end up with 60.
Take the next digit (9) from the dividend and append it to 60, then repeat: 609 / 420

Advancing to step 3:
If we divide 609 by 420, we get 1 and a remainder of 189.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 420 from 609, we get 189.
Append the next digit (9) from the dividend to 189 and continue with: 1899 / 420

Going ahead to step 4:
420 goes into 1899 4 times with a remainder of 219.
Use 4 as the next digit of our solution. 
Result so far: 14.0
The remainder is 219 after subtracting 1680 from 1899.
Grab the next digit (5) from the dividend, add it to 219, then carry on: 2195 / 420

Step 5:
2195 divided by 420 is 5 with a remainder of 95.
Write down 5 as next digit of the result. 
Result so far: 145.0
Subtract 2100 from 2195 to get 95.
Bring next digit (9) of the dividend behind the 95 and repeat the process: 959 / 420

Going ahead to step 6:
The number 420 fits into 959 2 times, leaving a remainder of 119.
Write down 2 as next digit of the result. 
Result so far: 1452.0
Subtract 840 from 959 to get 119.
Grab the next digit (6) from the dividend, add it to 119, then carry on: 1196 / 420

Advancing to step 7:
If we divide 1196 by 420, we get 2 and a remainder of 356.
Record the quotient 2 as the next digit in the result. 
Result so far: 14522.0
Subtracting 840 from 1196 leaves us with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

On to step 8:
420 goes into 3560 8 times with a remainder of 200.
Write down 8 as next digit of the result. 
Result so far: 14522.8
Deduct 3360 from 3560 and we're left 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.

Going ahead to step 9:
2000 divided by 420 is 4 with a remainder of 320.
The number 4 becomes the next digit in our result. 
Result so far: 14522.84
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.

Advancing to step 10:
When dividing 3200 by 420, we get 7 with a remainder of 260.
Write down 7 as next digit of the result. 
Result so far: 14522.847
If we take 2940 away from 3200, we end up with 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 11:
The number 420 fits into 2600 6 times, leaving a remainder of 80.
The next digit of our result is 6. 
Result so far: 14522.8476
The remainder is 80 after subtracting 2520 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 12:
800 divided by 420 is 1 with a remainder of 380.
The number 1 becomes the next digit in our result. 
Result so far: 14522.84761
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.

Let's proceed to step 13:
When dividing 3800 by 420, we get 9 with a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 14522.847619
Subtracting 3780 from 3800 leaves us 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.

On to step 14:
If we divide 200 by 420, we get 0 and a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 14522.847619
Deduct 0 from 200 and we're left 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.

Let's proceed to step 15:
420 goes into 2000 4 times with a remainder of 320.
The number 4 becomes the next digit in our result. 
Result so far: 14522.84761904
The remainder is 320 after subtracting 1680 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The final outcome is 14522.84761904, with a leftover of 3.2e-07.
