We look at the division of 66210931 by 371 
Our goal is to divide 66210931 by 371.

Moving on to step 1:
6 divided by 371 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 371

Moving on to step 2:
When dividing 66 by 371, we get 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Grab the next digit (2) from the dividend, add it to 66, then carry on: 662 / 371

Going ahead to step 3:
When dividing 662 by 371, we get 1 with a remainder of 291.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 371 from 662, we get 291.
Grab the next digit (1) from the dividend, add it to 291, then carry on: 2911 / 371

Advancing to step 4:
371 goes into 2911 7 times with a remainder of 314.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we take 2597 away from 2911, we end up with 314.
Take the next digit (0) from the dividend and append it to 314, then repeat: 3140 / 371

On to step 5:
The number 371 fits into 3140 8 times, leaving a remainder of 172.
Use 8 as the next digit of our solution. 
Result so far: 178.0
Deduct 2968 from 3140 and we're left with 172.
Append the next digit (9) from the dividend to 172 and continue with: 1729 / 371

Step 6:
1729 divided by 371 is 4 with a remainder of 245.
Use 4 as the next digit of our solution. 
Result so far: 1784.0
If we take 1484 away from 1729, we end up with 245.
Bring next digit (3) of the dividend behind the 245 and repeat the process: 2453 / 371

Going ahead to step 7:
371 goes into 2453 6 times with a remainder of 227.
The number 6 becomes the next digit in our result. 
Result so far: 17846.0
Subtracting 2226 from 2453 leaves us with 227.
Grab the next digit (1) from the dividend, add it to 227, then carry on: 2271 / 371

Advancing to step 8:
2271 divided by 371 is 6 with a remainder of 45.
The number 6 becomes the next digit in our result. 
Result so far: 178466.0
Subtract 2226 from 2271 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 9:
If we divide 450 by 371, we get 1 and a remainder of 79.
The number 1 becomes the next digit in our result. 
Result so far: 178466.1
The remainder is 79 after subtracting 371 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 10:
If we divide 790 by 371, we get 2 and a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 178466.12
Subtracting 742 from 790 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
The number 371 fits into 480 1 times, leaving a remainder of 109.
The number 1 becomes the next digit in our result. 
Result so far: 178466.121
The remainder is 109 after subtracting 371 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

On to step 12:
When dividing 1090 by 371, we get 2 with a remainder of 348.
Record the quotient 2 as the next digit in the result. 
Result so far: 178466.1212
If we subtract 742 from 1090, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Advancing to step 13:
371 goes into 3480 9 times with a remainder of 141.
Record the quotient 9 as the next digit in the result. 
Result so far: 178466.12129
Subtracting 3339 from 3480 leaves us with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

On to step 14:
1410 divided by 371 is 3 with a remainder of 297.
Use 3 as the next digit of our solution. 
Result so far: 178466.121293
Subtracting 1113 from 1410 leaves us with 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Let's proceed to step 15:
When dividing 2970 by 371, we get 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 178466.1212938
If we take 2968 away from 2970, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 16:
371 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 178466.1212938
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 178466.1212938 with a remainder of 2e-08.
