Let's divide 250021 by 66
Our goal is to divide 250021 by 66.

Going ahead to step 1:
The number 66 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 66

Moving on to step 2:
When dividing 25 by 66, we get 0 with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Append the next digit (0) from the dividend to 25 and continue with: 250 / 66

Let's proceed to step 3:
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: 3.0
If we take 198 away from 250, we end up with 52.
Include the next digit (0) from the dividend after 52, then repeat: 520 / 66

Let's proceed to step 4:
66 can be fit into 520 7 times, resulting in a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Subtracting 462 from 520 leaves us with 58.
Take the next digit (2) from the dividend and append it to 58, then repeat: 582 / 66

Step 5:
582 divided by 66 is 8 with a remainder of 54.
The number 8 becomes the next digit in our result. 
Result so far: 378.0
If we subtract 528 from 582, we get 54.
Grab the next digit (1) from the dividend, add it to 54, then carry on: 541 / 66

Going ahead to step 6:
66 goes into 541 8 times with a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 3788.0
The remainder is 13 after subtracting 528 from 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
The number 66 fits into 130 1 times, leaving a remainder of 64.
Put 1 as the next digit of the answer. 
Result so far: 3788.1
Deduct 66 from 130 and we're left 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.

Let's proceed to step 8:
66 can be fit into 640 9 times, resulting in a remainder of 46.
The next digit of our result is 9. 
Result so far: 3788.19
If we subtract 594 from 640, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 9:
460 divided by 66 is 6 with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 3788.196
Deduct 396 from 460 and we're left 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 10:
66 goes into 640 9 times with a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 3788.1969
If we subtract 594 from 640, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 11:
66 can be fit into 460 6 times, resulting in a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 3788.19696
Deduct 396 from 460 and we're left 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.

Going ahead to step 12:
If we divide 640 by 66, we get 9 and a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 3788.196969
Deduct 594 from 640 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 13:
The number 66 fits into 460 6 times, leaving a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 3788.1969696
Subtract 396 from 460 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 14:
If we divide 640 by 66, we get 9 and a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 3788.19696969
Subtract 594 from 640 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Our division results in 3788.19696969 with a remaining 4.6e-08.
