Let's divide 375143 by 66
Our goal is to divide 375143 by 66.

Advancing to step 1:
The number 66 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 66

Going ahead to step 2:
66 goes into 37 0 times with a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Include the next digit (5) from the dividend after 37, then repeat: 375 / 66

Advancing to step 3:
The number 66 fits into 375 5 times, leaving a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 330 from 375 leaves us with 45.
Grab the next digit (1) from the dividend, add it to 45, then carry on: 451 / 66

Moving on to step 4:
451 divided by 66 is 6 with a remainder of 55.
Write down 6 as next digit of the result. 
Result so far: 56.0
Deduct 396 from 451 and we're left with 55.
Grab the next digit (4) from the dividend, add it to 55, then carry on: 554 / 66

On to step 5:
66 can be fit into 554 8 times, resulting in a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 568.0
If we take 528 away from 554, we end up with 26.
Grab the next digit (3) from the dividend, add it to 26, then carry on: 263 / 66

Advancing to step 6:
66 can be fit into 263 3 times, resulting in a remainder of 65.
Use 3 as the next digit of our solution. 
Result so far: 5683.0
Deduct 198 from 263 and we're left with 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 7:
The number 66 fits into 650 9 times, leaving a remainder of 56.
Write down 9 as next digit of the result. 
Result so far: 5683.9
The remainder is 56 after subtracting 594 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 8:
66 goes into 560 8 times with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 5683.98
Subtract 528 from 560 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
320 divided by 66 is 4 with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 5683.984
If we take 264 away from 320, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 10:
66 goes into 560 8 times with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 5683.9848
If we subtract 528 from 560, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 11:
If we divide 320 by 66, we get 4 and a remainder of 56.
The next digit of our result is 4. 
Result so far: 5683.98484
The remainder is 56 after subtracting 264 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 12:
The number 66 fits into 560 8 times, leaving a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 5683.984848
Subtracting 528 from 560 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 13:
320 divided by 66 is 4 with a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 5683.9848484
Subtracting 264 from 320 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 14:
66 can be fit into 560 8 times, resulting in a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 5683.98484848
Subtracting 528 from 560 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 5683.98484848 with a remainder of 3.2e-08.
