Let's divide 165901 by 51
We want to figure out the number of times 165901 can be divided by 51.

Going ahead to step 1:
1 divided by 51 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 51

Moving on to step 2:
51 can be fit into 16 0 times, resulting in a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Fetch the next digit (5) from the dividend, attach it to 16 and continue: 165 / 51

Moving on to step 3:
165 divided by 51 is 3 with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 153 away from 165, we end up with 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 51

Going ahead to step 4:
51 can be fit into 129 2 times, resulting in a remainder of 27.
Use 2 as the next digit of our solution. 
Result so far: 32.0
Subtract 102 from 129 to get 27.
Include the next digit (0) from the dividend after 27, then repeat: 270 / 51

Step 5:
51 goes into 270 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 325.0
If we take 255 away from 270, we end up with 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 51

Moving on to step 6:
If we divide 151 by 51, we get 2 and a remainder of 49.
Put 2 as the next digit of the answer. 
Result so far: 3252.0
The remainder is 49 after subtracting 102 from 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 7:
If we divide 490 by 51, we get 9 and a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 3252.9
Subtracting 459 from 490 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 8:
310 divided by 51 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 3252.96
Deduct 306 from 310 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
The number 51 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 3252.96
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
51 can be fit into 400 7 times, resulting in a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 3252.9607
The remainder is 43 after subtracting 357 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 11:
The number 51 fits into 430 8 times, leaving a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 3252.96078
Subtract 408 from 430 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 12:
The number 51 fits into 220 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 3252.960784
The remainder is 16 after subtracting 204 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
51 goes into 160 3 times with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 3252.9607843
Subtracting 153 from 160 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 14:
If we divide 70 by 51, we get 1 and a remainder of 19.
The next digit of our result is 1. 
Result so far: 3252.96078431
Subtracting 51 from 70 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

In conclusion, the division gives 3252.96078431 with a balance of 1.9e-08.
