Let's divide 166641 by 51
Our goal is to divide 166641 by 51.

Going ahead to step 1:
The number 51 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 51

Let's proceed to step 2:
51 can be fit into 16 0 times, resulting in a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 51

Going ahead to step 3:
51 goes into 166 3 times with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 153 from 166 leaves us with 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 51

Going ahead to step 4:
136 divided by 51 is 2 with a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 32.0
Deduct 102 from 136 and we're left with 34.
Fetch the next digit (4) from the dividend, attach it to 34 and continue: 344 / 51

Advancing to step 5:
The number 51 fits into 344 6 times, leaving a remainder of 38.
Record the quotient 6 as the next digit in the result. 
Result so far: 326.0
If we take 306 away from 344, we end up with 38.
Include the next digit (1) from the dividend after 38, then repeat: 381 / 51

On to step 6:
51 can be fit into 381 7 times, resulting in a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 3267.0
The remainder is 24 after subtracting 357 from 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 7:
51 can be fit into 240 4 times, resulting in a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 3267.4
The remainder is 36 after subtracting 204 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 8:
51 goes into 360 7 times with a remainder of 3.
The next digit of our result is 7. 
Result so far: 3267.47
Subtracting 357 from 360 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
When dividing 30 by 51, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 3267.47
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
If we divide 300 by 51, we get 5 and a remainder of 45.
The next digit of our result is 5. 
Result so far: 3267.4705
Deduct 255 from 300 and we're left with 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 11:
When dividing 450 by 51, we get 8 with a remainder of 42.
The next digit of our result is 8. 
Result so far: 3267.47058
Subtract 408 from 450 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 12:
If we divide 420 by 51, we get 8 and a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 3267.470588
Subtracting 408 from 420 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 3267.470588 with a balance of 1.2e-06.
