We divide 851431 by 46
We want to divide 851431 by 46.

Moving on to step 1:
8 divided by 46 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 46

Moving on to step 2:
If we divide 85 by 46, we get 1 and a remainder of 39.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 39 after subtracting 46 from 85.
Take the next digit (1) from the dividend and append it to 39, then repeat: 391 / 46

Moving on to step 3:
If we divide 391 by 46, we get 8 and a remainder of 23.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we take 368 away from 391, we end up with 23.
Append the next digit (4) from the dividend to 23 and continue with: 234 / 46

Moving on to step 4:
46 goes into 234 5 times with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 185.0
Deduct 230 from 234 and we're left with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 46

On to step 5:
46 goes into 43 0 times with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 1850.0
The remainder is 43 after subtracting 0 from 43.
Include the next digit (1) from the dividend after 43, then repeat: 431 / 46

On to step 6:
The number 46 fits into 431 9 times, leaving a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 18509.0
If we subtract 414 from 431, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
When dividing 170 by 46, we get 3 with a remainder of 32.
Write down 3 as next digit of the result. 
Result so far: 18509.3
Subtracting 138 from 170 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 8:
If we divide 320 by 46, we get 6 and a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 18509.36
If we subtract 276 from 320, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 9:
46 goes into 440 9 times with a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 18509.369
Deduct 414 from 440 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 10:
46 can be fit into 260 5 times, resulting in a remainder of 30.
The next digit of our result is 5. 
Result so far: 18509.3695
Deduct 230 from 260 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.

On to step 11:
If we divide 300 by 46, we get 6 and a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 18509.36956
Subtract 276 from 300 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 12:
The number 46 fits into 240 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 18509.369565
Subtract 230 from 240 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 13:
If we divide 100 by 46, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 18509.3695652
Deduct 92 from 100 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 14:
If we divide 80 by 46, we get 1 and a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 18509.36956521
Subtract 46 from 80 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 18509.36956521, with a leftover of 3.4e-08.
