48891 ÷ 51 
We want to figure out the number of times 48891 can be divided by 51.

Step 1:
If we divide 4 by 51, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 51

Let's proceed to step 2:
If we divide 48 by 51, we get 0 and a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 48 leaves us with 48.
Grab the next digit (8) from the dividend, add it to 48, then carry on: 488 / 51

Step 3:
When dividing 488 by 51, we get 9 with a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 459 from 488 to get 29.
Grab the next digit (9) from the dividend, add it to 29, then carry on: 299 / 51

Step 4:
The number 51 fits into 299 5 times, leaving a remainder of 44.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
If we subtract 255 from 299, we get 44.
Fetch the next digit (1) from the dividend, attach it to 44 and continue: 441 / 51

Step 5:
When dividing 441 by 51, we get 8 with a remainder of 33.
Record the quotient 8 as the next digit in the result. 
Result so far: 958.0
Subtract 408 from 441 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 6:
330 divided by 51 is 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 958.6
Deduct 306 from 330 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 7:
240 divided by 51 is 4 with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 958.64
If we take 204 away from 240, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 8:
51 can be fit into 360 7 times, resulting in a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 958.647
Subtract 357 from 360 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 9:
The number 51 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 958.647
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
51 can be fit into 300 5 times, resulting in a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 958.64705
If we subtract 255 from 300, we 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.

Step 11:
51 can be fit into 450 8 times, resulting in a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 958.647058
The remainder is 42 after subtracting 408 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 12:
The number 51 fits into 420 8 times, leaving a remainder of 12.
The next digit of our result is 8. 
Result so far: 958.6470588
Deduct 408 from 420 and we're left 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.

After the division, we end up with 958.6470588 and a remainder of 1.2e-07.
