426148 divided by 51 
We want to figure out the number of times 426148 can be divided by 51.

Going ahead to step 1:
51 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 51

On to step 2:
The number 51 fits into 42 0 times, leaving a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Append the next digit (6) from the dividend to 42 and continue with: 426 / 51

Advancing to step 3:
51 goes into 426 8 times with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 408 from 426 leaves us with 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 51

Moving on to step 4:
If we divide 181 by 51, we get 3 and a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 83.0
Subtract 153 from 181 to get 28.
Take the next digit (4) from the dividend and append it to 28, then repeat: 284 / 51

Let's proceed to step 5:
When dividing 284 by 51, we get 5 with a remainder of 29.
Write down 5 as next digit of the result. 
Result so far: 835.0
The remainder is 29 after subtracting 255 from 284.
Fetch the next digit (8) from the dividend, attach it to 29 and continue: 298 / 51

Moving on to step 6:
51 goes into 298 5 times with a remainder of 43.
The number 5 becomes the next digit in our result. 
Result so far: 8355.0
Subtracting 255 from 298 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 7:
51 can be fit into 430 8 times, resulting in a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 8355.8
If we take 408 away from 430, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
If we divide 220 by 51, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 8355.84
Subtracting 204 from 220 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
51 can be fit into 160 3 times, resulting in a remainder of 7.
The next digit of our result is 3. 
Result so far: 8355.843
If we subtract 153 from 160, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 10:
51 can be fit into 70 1 times, resulting in a remainder of 19.
The next digit of our result is 1. 
Result so far: 8355.8431
The remainder is 19 after subtracting 51 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 11:
The number 51 fits into 190 3 times, leaving a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 8355.84313
Deduct 153 from 190 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 12:
51 can be fit into 370 7 times, resulting in a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 8355.843137
If we take 357 away from 370, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 13:
130 divided by 51 is 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 8355.8431372
Subtract 102 from 130 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 14:
The number 51 fits into 280 5 times, leaving a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 8355.84313725
If we take 255 away from 280, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

In conclusion, the division gives 8355.84313725 with a balance of 2.5e-08.
