Let's divide 426415 by 51
Let's see how many times 51 fits into 426415.

Advancing to step 1:
4 divided by 51 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 51

Step 2:
51 goes into 42 0 times with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Grab the next digit (6) from the dividend, add it to 42, then carry on: 426 / 51

Moving on to step 3:
51 goes into 426 8 times with a remainder of 18.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 408 from 426 and we're left with 18.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 51

Advancing to step 4:
51 can be fit into 184 3 times, resulting in a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 83.0
Subtracting 153 from 184 leaves us with 31.
Append the next digit (1) from the dividend to 31 and continue with: 311 / 51

Going ahead to step 5:
51 can be fit into 311 6 times, resulting in a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 836.0
The remainder is 5 after subtracting 306 from 311.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 51

On to step 6:
The number 51 fits into 55 1 times, leaving a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 8361.0
Subtracting 51 from 55 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
If we divide 40 by 51, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 8361.0
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
When dividing 400 by 51, we get 7 with a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 8361.07
If we subtract 357 from 400, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 9:
When dividing 430 by 51, we get 8 with a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 8361.078
Subtract 408 from 430 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 10:
220 divided by 51 is 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 8361.0784
Deduct 204 from 220 and we're left 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.

Going ahead to step 11:
The number 51 fits into 160 3 times, leaving a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 8361.07843
If we take 153 away from 160, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 12:
51 can be fit into 70 1 times, resulting in a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 8361.078431
Subtract 51 from 70 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 13:
When dividing 190 by 51, we get 3 with a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 8361.0784313
If we subtract 153 from 190, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 14:
The number 51 fits into 370 7 times, leaving a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 8361.07843137
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.

The final outcome is 8361.07843137, with a leftover of 1.3e-08.
