We look at the division of 434053 by 51 
Let's see how many times 51 fits into 434053.

Moving on to step 1:
51 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 51

Moving on to step 2:
51 goes into 43 0 times with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Fetch the next digit (4) from the dividend, attach it to 43 and continue: 434 / 51

Advancing to step 3:
When dividing 434 by 51, we get 8 with a remainder of 26.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 408 from 434 leaves us with 26.
Bring next digit (0) of the dividend behind the 26 and repeat the process: 260 / 51

On to step 4:
When dividing 260 by 51, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
Deduct 255 from 260 and we're left with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 51

Going ahead to step 5:
When dividing 55 by 51, we get 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 851.0
Subtracting 51 from 55 leaves us with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 51

Going ahead to step 6:
When dividing 43 by 51, we get 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 8510.0
Subtract 0 from 43 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 7:
430 divided by 51 is 8 with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 8510.8
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.

Going ahead to step 8:
When dividing 220 by 51, we get 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 8510.84
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.

Moving on to step 9:
The number 51 fits into 160 3 times, leaving a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 8510.843
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.

On to step 10:
70 divided by 51 is 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 8510.8431
If we take 51 away from 70, we end up 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.

Moving on to step 11:
51 can be fit into 190 3 times, resulting in a remainder of 37.
The next digit of our result is 3. 
Result so far: 8510.84313
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.

On to step 12:
If we divide 370 by 51, we get 7 and a remainder of 13.
The next digit of our result is 7. 
Result so far: 8510.843137
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.

Step 13:
When dividing 130 by 51, we get 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 8510.8431372
Subtracting 102 from 130 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 14:
51 goes into 280 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 8510.84313725
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.

After the division, we end up with 8510.84313725 and a remainder of 2.5e-08.
