Let's divide 423846 by 51
Let's see how many times 51 fits into 423846.

Advancing to step 1:
If we divide 4 by 51, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 51

Going ahead to step 2:
51 can be fit into 42 0 times, resulting in a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Append the next digit (3) from the dividend to 42 and continue with: 423 / 51

Let's proceed to step 3:
51 can be fit into 423 8 times, resulting in a remainder of 15.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 408 from 423 and we're left with 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 51

On to step 4:
When dividing 158 by 51, we get 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
Subtracting 153 from 158 leaves us with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 51

On to step 5:
If we divide 54 by 51, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 831.0
The remainder is 3 after subtracting 51 from 54.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 51

Advancing to step 6:
51 can be fit into 36 0 times, resulting in a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 8310.0
The remainder is 36 after subtracting 0 from 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 7:
360 divided by 51 is 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 8310.7
If we take 357 away from 360, we end up with 3.
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 8:
If we divide 30 by 51, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 8310.7
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.

Going ahead to step 9:
51 goes into 300 5 times with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 8310.705
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.

Moving on to step 10:
51 can be fit into 450 8 times, resulting in a remainder of 42.
The next digit of our result is 8. 
Result so far: 8310.7058
Deduct 408 from 450 and we're left 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.

Step 11:
If we divide 420 by 51, we get 8 and a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 8310.70588
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 8310.70588 and a remainder of 1.2e-05.
