We divide 420920 by 66
Our goal is to divide 420920 by 66.

Going ahead to step 1:
When dividing 4 by 66, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 66

Moving on to step 2:
The number 66 fits into 42 0 times, leaving a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 66

Step 3:
66 goes into 420 6 times with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 24 after subtracting 396 from 420.
Fetch the next digit (9) from the dividend, attach it to 24 and continue: 249 / 66

Moving on to step 4:
66 can be fit into 249 3 times, resulting in a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 63.0
Subtracting 198 from 249 leaves us with 51.
Grab the next digit (2) from the dividend, add it to 51, then carry on: 512 / 66

Advancing to step 5:
66 goes into 512 7 times with a remainder of 50.
Put 7 as the next digit of the answer. 
Result so far: 637.0
Deduct 462 from 512 and we're left with 50.
Grab the next digit (0) from the dividend, add it to 50, then carry on: 500 / 66

Going ahead to step 6:
500 divided by 66 is 7 with a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 6377.0
Subtract 462 from 500 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 7:
If we divide 380 by 66, we get 5 and a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 6377.5
If we take 330 away from 380, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
66 can be fit into 500 7 times, resulting in a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 6377.57
Deduct 462 from 500 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 9:
66 goes into 380 5 times with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 6377.575
The remainder is 50 after subtracting 330 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
66 can be fit into 500 7 times, resulting in a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 6377.5757
Deduct 462 from 500 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 11:
66 goes into 380 5 times with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 6377.57575
Subtracting 330 from 380 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
The number 66 fits into 500 7 times, leaving a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 6377.575757
Deduct 462 from 500 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 13:
If we divide 380 by 66, we get 5 and a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 6377.5757575
Subtracting 330 from 380 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 14:
66 can be fit into 500 7 times, resulting in a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 6377.57575757
Deduct 462 from 500 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final result is 6377.57575757 with a remainder of 3.8e-08.
