We're dividing 45954 by 51 
We want to figure out the number of times 45954 can be divided by 51.

Moving on to step 1:
When dividing 4 by 51, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 51

Let's proceed to step 2:
The number 51 fits into 45 0 times, leaving a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Fetch the next digit (9) from the dividend, attach it to 45 and continue: 459 / 51

Step 3:
51 goes into 459 9 times with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 459 from 459 and we're left with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 51

Step 4:
When dividing 5 by 51, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 90.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 51

On to step 5:
51 can be fit into 54 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 901.0
The remainder is 3 after subtracting 51 from 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 6:
51 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 901.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 7:
51 can be fit into 300 5 times, resulting in a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 901.05
Subtract 255 from 300 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 8:
The number 51 fits into 450 8 times, leaving a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 901.058
Subtracting 408 from 450 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 9:
If we divide 420 by 51, we get 8 and a remainder of 12.
The next digit of our result is 8. 
Result so far: 901.0588
If we take 408 away from 420, we end up 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.

The final result is 901.0588 with a remainder of 0.00012.
