418435 ÷ 51 
Our goal is to divide 418435 by 51.

On to step 1:
The number 51 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 51

Step 2:
The number 51 fits into 41 0 times, leaving a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 41, we end up with 41.
Fetch the next digit (8) from the dividend, attach it to 41 and continue: 418 / 51

On to step 3:
51 goes into 418 8 times with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 408 away from 418, we end up with 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 51

Step 4:
104 divided by 51 is 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
Deduct 102 from 104 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 51

On to step 5:
23 divided by 51 is 0 with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 820.0
Deduct 0 from 23 and we're left with 23.
Append the next digit (5) from the dividend to 23 and continue with: 235 / 51

Step 6:
51 can be fit into 235 4 times, resulting in a remainder of 31.
Use 4 as the next digit of our solution. 
Result so far: 8204.0
If we subtract 204 from 235, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 7:
The number 51 fits into 310 6 times, leaving a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 8204.6
If we subtract 306 from 310, we get 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 8:
51 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 8204.6
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.

Advancing to step 9:
51 goes into 400 7 times with a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 8204.607
Subtract 357 from 400 to 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.

Moving on to step 10:
If we divide 430 by 51, we get 8 and a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 8204.6078
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.

On to step 11:
51 can be fit into 220 4 times, resulting in a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 8204.60784
Subtract 204 from 220 to get 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 12:
If we divide 160 by 51, we get 3 and a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 8204.607843
Subtract 153 from 160 to 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.

On to step 13:
51 goes into 70 1 times with a remainder of 19.
The next digit of our result is 1. 
Result so far: 8204.6078431
Subtracting 51 from 70 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 14:
When dividing 190 by 51, we get 3 with a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 8204.60784313
The remainder is 37 after subtracting 153 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The final result is 8204.60784313 with a remainder of 3.7e-08.
