We're dividing 46149 by 51 
Our goal is to divide 46149 by 51.

Step 1:
51 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 51

Let's proceed to step 2:
If we divide 46 by 51, we get 0 and a remainder of 46.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 46, we get 46.
Bring next digit (1) of the dividend behind the 46 and repeat the process: 461 / 51

Step 3:
51 can be fit into 461 9 times, resulting in a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 459 from 461 and we're left with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 51

On to step 4:
If we divide 24 by 51, we get 0 and a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
Deduct 0 from 24 and we're left with 24.
Grab the next digit (9) from the dividend, add it to 24, then carry on: 249 / 51

Let's proceed to step 5:
The number 51 fits into 249 4 times, leaving a remainder of 45.
Use 4 as the next digit of our solution. 
Result so far: 904.0
Deduct 204 from 249 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.

Going ahead to step 6:
The number 51 fits into 450 8 times, leaving a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 904.8
If we subtract 408 from 450, we 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.

Going ahead to step 7:
When dividing 420 by 51, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 904.88
Subtract 408 from 420 to get 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 quotient of the division is 904.88, and the remainder is 0.012.
