We look at the division of 189754 by 51 
We want to figure out the number of times 189754 can be divided by 51.

Step 1:
1 divided by 51 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 51

Step 2:
The number 51 fits into 18 0 times, leaving a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 51

Advancing to step 3:
51 can be fit into 189 3 times, resulting in a remainder of 36.
The next digit of our result is 3. 
Result so far: 3.0
If we take 153 away from 189, we end up with 36.
Grab the next digit (7) from the dividend, add it to 36, then carry on: 367 / 51

On to step 4:
If we divide 367 by 51, we get 7 and a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 37.0
The remainder is 10 after subtracting 357 from 367.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 51

Advancing to step 5:
The number 51 fits into 105 2 times, leaving a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 372.0
The remainder is 3 after subtracting 102 from 105.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 51

Advancing to step 6:
When dividing 34 by 51, we get 0 with a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 3720.0
Deduct 0 from 34 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
51 can be fit into 340 6 times, resulting in a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 3720.6
Subtract 306 from 340 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 8:
When dividing 340 by 51, we get 6 with a remainder of 34.
The next digit of our result is 6. 
Result so far: 3720.66
Subtract 306 from 340 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The quotient of the division is 3720.66, and the remainder is 0.034.
