428147 ÷ 51 
We're looking to find how many times 51 goes into 428147.

Step 1:
51 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 51

Going ahead to step 2:
42 divided by 51 is 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Bring next digit (8) of the dividend behind the 42 and repeat the process: 428 / 51

Going ahead to step 3:
The number 51 fits into 428 8 times, leaving a remainder of 20.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 20 after subtracting 408 from 428.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 51

Step 4:
If we divide 201 by 51, we get 3 and a remainder of 48.
Record the quotient 3 as the next digit in the result. 
Result so far: 83.0
Subtract 153 from 201 to get 48.
Grab the next digit (4) from the dividend, add it to 48, then carry on: 484 / 51

Step 5:
When dividing 484 by 51, we get 9 with a remainder of 25.
Put 9 as the next digit of the answer. 
Result so far: 839.0
If we take 459 away from 484, we end up with 25.
Include the next digit (7) from the dividend after 25, then repeat: 257 / 51

Going ahead to step 6:
257 divided by 51 is 5 with a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 8395.0
Subtract 255 from 257 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
The number 51 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 8395.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
The number 51 fits into 200 3 times, leaving a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 8395.03
If we subtract 153 from 200, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 9:
51 goes into 470 9 times with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 8395.039
Subtract 459 from 470 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 10:
If we divide 110 by 51, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 8395.0392
Deduct 102 from 110 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
When dividing 80 by 51, we get 1 with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 8395.03921
Subtract 51 from 80 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 12:
If we divide 290 by 51, we get 5 and a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 8395.039215
If we subtract 255 from 290, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 13:
The number 51 fits into 350 6 times, leaving a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 8395.0392156
Subtracting 306 from 350 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 14:
51 can be fit into 440 8 times, resulting in a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 8395.03921568
The remainder is 32 after subtracting 408 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 8395.03921568, and the remainder is 3.2e-08.
