168661 divided by 51 
Let's see how many times 51 fits into 168661.

Let's proceed to step 1:
1 divided by 51 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 51

Going ahead to step 2:
16 divided by 51 is 0 with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 51

On to step 3:
168 divided by 51 is 3 with a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 153 from 168 leaves us with 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 51

Let's proceed to step 4:
51 can be fit into 156 3 times, resulting in a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 33.0
If we subtract 153 from 156, we get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 51

Advancing to step 5:
51 goes into 36 0 times with a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 330.0
Deduct 0 from 36 and we're left with 36.
Take the next digit (1) from the dividend and append it to 36, then repeat: 361 / 51

Advancing to step 6:
361 divided by 51 is 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 3307.0
Subtracting 357 from 361 leaves us 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.

On to step 7:
51 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 3307.0
Subtract 0 from 40 to 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.

Going ahead to step 8:
If we divide 400 by 51, we get 7 and a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 3307.07
Subtract 357 from 400 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 9:
If we divide 430 by 51, we get 8 and a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 3307.078
The remainder is 22 after subtracting 408 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 10:
When dividing 220 by 51, we get 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 3307.0784
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.

Moving on to step 11:
51 can be fit into 160 3 times, resulting in a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 3307.07843
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.

Let's proceed to step 12:
70 divided by 51 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 3307.078431
If we take 51 away from 70, we end up 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.

Going ahead to step 13:
51 can be fit into 190 3 times, resulting in a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 3307.0784313
If we subtract 153 from 190, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 14:
51 goes into 370 7 times with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 3307.07843137
If we take 357 away from 370, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

In conclusion, the division gives 3307.07843137 with a balance of 1.3e-08.
