We look at the division of 420495 by 83 
We want to figure out the number of times 420495 can be divided by 83.

Let's proceed to step 1:
The number 83 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 83

Step 2:
83 can be fit into 42 0 times, resulting in a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 83

On to step 3:
When dividing 420 by 83, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 415 from 420, we get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 83

Step 4:
If we divide 54 by 83, we get 0 and a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Subtracting 0 from 54 leaves us with 54.
Take the next digit (9) from the dividend and append it to 54, then repeat: 549 / 83

Going ahead to step 5:
The number 83 fits into 549 6 times, leaving a remainder of 51.
The next digit of our result is 6. 
Result so far: 506.0
If we take 498 away from 549, we end up with 51.
Grab the next digit (5) from the dividend, add it to 51, then carry on: 515 / 83

Moving on to step 6:
The number 83 fits into 515 6 times, leaving a remainder of 17.
Write down 6 as next digit of the result. 
Result so far: 5066.0
Subtracting 498 from 515 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
The number 83 fits into 170 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 5066.2
Deduct 166 from 170 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
The number 83 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 5066.2
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
83 can be fit into 400 4 times, resulting in a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 5066.204
If we take 332 away from 400, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 10:
83 goes into 680 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 5066.2048
Subtracting 664 from 680 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
83 goes into 160 1 times with a remainder of 77.
Use 1 as the next digit of our solution. 
Result so far: 5066.20481
Subtracting 83 from 160 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 12:
83 can be fit into 770 9 times, resulting in a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 5066.204819
The remainder is 23 after subtracting 747 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 13:
230 divided by 83 is 2 with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 5066.2048192
Subtracting 166 from 230 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 14:
640 divided by 83 is 7 with a remainder of 59.
The next digit of our result is 7. 
Result so far: 5066.20481927
The remainder is 59 after subtracting 581 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

After the division, we end up with 5066.20481927 and a remainder of 5.9e-08.
