We divide 621943 by 66
Our goal is to divide 621943 by 66.

Going ahead to step 1:
The number 66 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 66

Step 2:
When dividing 62 by 66, we get 0 with a remainder of 62.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 62 to get 62.
Take the next digit (1) from the dividend and append it to 62, then repeat: 621 / 66

Advancing to step 3:
If we divide 621 by 66, we get 9 and a remainder of 27.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 594 from 621 and we're left with 27.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 66

Going ahead to step 4:
The number 66 fits into 279 4 times, leaving a remainder of 15.
The next digit of our result is 4. 
Result so far: 94.0
The remainder is 15 after subtracting 264 from 279.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 66

Step 5:
The number 66 fits into 154 2 times, leaving a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 942.0
The remainder is 22 after subtracting 132 from 154.
Take the next digit (3) from the dividend and append it to 22, then repeat: 223 / 66

Moving on to step 6:
The number 66 fits into 223 3 times, leaving a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 9423.0
Deduct 198 from 223 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 7:
66 can be fit into 250 3 times, resulting in a remainder of 52.
The next digit of our result is 3. 
Result so far: 9423.3
Subtract 198 from 250 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 8:
66 can be fit into 520 7 times, resulting in a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 9423.37
The remainder is 58 after subtracting 462 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 9:
66 goes into 580 8 times with a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 9423.378
Deduct 528 from 580 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 10:
520 divided by 66 is 7 with a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 9423.3787
Subtract 462 from 520 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 11:
66 goes into 580 8 times with a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 9423.37878
Deduct 528 from 580 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 12:
66 goes into 520 7 times with a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 9423.378787
Subtract 462 from 520 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 13:
The number 66 fits into 580 8 times, leaving a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 9423.3787878
Subtract 528 from 580 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 14:
The number 66 fits into 520 7 times, leaving a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 9423.37878787
Deduct 462 from 520 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Our division results in 9423.37878787 with a remaining 5.8e-08.
