Let's divide 66242021 by 419
We want to divide 66242021 by 419.

Going ahead to step 1:
When dividing 6 by 419, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 419

Moving on to step 2:
If we divide 66 by 419, we get 0 and a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Fetch the next digit (2) from the dividend, attach it to 66 and continue: 662 / 419

On to step 3:
419 goes into 662 1 times with a remainder of 243.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 419 away from 662, we end up with 243.
Bring next digit (4) of the dividend behind the 243 and repeat the process: 2434 / 419

Step 4:
419 goes into 2434 5 times with a remainder of 339.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 2095 away from 2434, we end up with 339.
Grab the next digit (2) from the dividend, add it to 339, then carry on: 3392 / 419

On to step 5:
3392 divided by 419 is 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 158.0
If we subtract 3352 from 3392, we get 40.
Fetch the next digit (0) from the dividend, attach it to 40 and continue: 400 / 419

Going ahead to step 6:
When dividing 400 by 419, we get 0 with a remainder of 400.
The next digit of our result is 0. 
Result so far: 1580.0
Subtracting 0 from 400 leaves us with 400.
Include the next digit (2) from the dividend after 400, then repeat: 4002 / 419

Moving on to step 7:
If we divide 4002 by 419, we get 9 and a remainder of 231.
Write down 9 as next digit of the result. 
Result so far: 15809.0
If we subtract 3771 from 4002, we get 231.
Grab the next digit (1) from the dividend, add it to 231, then carry on: 2311 / 419

Moving on to step 8:
If we divide 2311 by 419, we get 5 and a remainder of 216.
Put 5 as the next digit of the answer. 
Result so far: 158095.0
Deduct 2095 from 2311 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 9:
When dividing 2160 by 419, we get 5 with a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 158095.5
Subtract 2095 from 2160 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 10:
419 goes into 650 1 times with a remainder of 231.
Put 1 as the next digit of the answer. 
Result so far: 158095.51
If we take 419 away from 650, we end up with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Going ahead to step 11:
419 goes into 2310 5 times with a remainder of 215.
The next digit of our result is 5. 
Result so far: 158095.515
Subtract 2095 from 2310 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Going ahead to step 12:
When dividing 2150 by 419, we get 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 158095.5155
If we subtract 2095 from 2150, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final result is 158095.5155 with a remainder of 0.00055.
