We look at the division of 851950 by 455 
We want to divide 851950 by 455.

Advancing to step 1:
If we divide 8 by 455, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 455

Step 2:
455 goes into 85 0 times with a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Bring next digit (1) of the dividend behind the 85 and repeat the process: 851 / 455

On to step 3:
455 goes into 851 1 times with a remainder of 396.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 455 from 851 and we're left with 396.
Fetch the next digit (9) from the dividend, attach it to 396 and continue: 3969 / 455

Let's proceed to step 4:
455 can be fit into 3969 8 times, resulting in a remainder of 329.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we subtract 3640 from 3969, we get 329.
Append the next digit (5) from the dividend to 329 and continue with: 3295 / 455

Moving on to step 5:
455 goes into 3295 7 times with a remainder of 110.
The number 7 becomes the next digit in our result. 
Result so far: 187.0
If we take 3185 away from 3295, we end up with 110.
Fetch the next digit (0) from the dividend, attach it to 110 and continue: 1100 / 455

Moving on to step 6:
The number 455 fits into 1100 2 times, leaving a remainder of 190.
Write down 2 as next digit of the result. 
Result so far: 1872.0
Deduct 910 from 1100 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 7:
455 can be fit into 1900 4 times, resulting in a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 1872.4
The remainder is 80 after subtracting 1820 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 8:
If we divide 800 by 455, we get 1 and a remainder of 345.
Record the quotient 1 as the next digit in the result. 
Result so far: 1872.41
If we subtract 455 from 800, we get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

On to step 9:
455 can be fit into 3450 7 times, resulting in a remainder of 265.
Use 7 as the next digit of our solution. 
Result so far: 1872.417
Subtracting 3185 from 3450 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

On to step 10:
When dividing 2650 by 455, we get 5 with a remainder of 375.
Record the quotient 5 as the next digit in the result. 
Result so far: 1872.4175
If we subtract 2275 from 2650, we get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Step 11:
If we divide 3750 by 455, we get 8 and a remainder of 110.
The number 8 becomes the next digit in our result. 
Result so far: 1872.41758
Subtracting 3640 from 3750 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 12:
When dividing 1100 by 455, we get 2 with a remainder of 190.
Write down 2 as next digit of the result. 
Result so far: 1872.417582
Deduct 910 from 1100 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 13:
The number 455 fits into 1900 4 times, leaving a remainder of 80.
Put 4 as the next digit of the answer. 
Result so far: 1872.4175824
If we subtract 1820 from 1900, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 14:
800 divided by 455 is 1 with a remainder of 345.
Record the quotient 1 as the next digit in the result. 
Result so far: 1872.41758241
If we subtract 455 from 800, we get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

The final outcome is 1872.41758241, with a leftover of 3.45e-07.
