We look at the division of 868406 by 46 
We want to figure out the number of times 868406 can be divided by 46.

Advancing to step 1:
When dividing 8 by 46, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 46

On to step 2:
46 goes into 86 1 times with a remainder of 40.
The next digit of our result is 1. 
Result so far: 1.0
If we take 46 away from 86, we end up with 40.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 46

Moving on to step 3:
46 goes into 408 8 times with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 18.0
Deduct 368 from 408 and we're left with 40.
Take the next digit (4) from the dividend and append it to 40, then repeat: 404 / 46

Let's proceed to step 4:
46 can be fit into 404 8 times, resulting in a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 188.0
If we subtract 368 from 404, we get 36.
Append the next digit (0) from the dividend to 36 and continue with: 360 / 46

Let's proceed to step 5:
If we divide 360 by 46, we get 7 and a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 1887.0
If we subtract 322 from 360, we get 38.
Take the next digit (6) from the dividend and append it to 38, then repeat: 386 / 46

Moving on to step 6:
386 divided by 46 is 8 with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 18878.0
Subtracting 368 from 386 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
The number 46 fits into 180 3 times, leaving a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 18878.3
Deduct 138 from 180 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 8:
The number 46 fits into 420 9 times, leaving a remainder of 6.
The next digit of our result is 9. 
Result so far: 18878.39
Subtracting 414 from 420 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
46 goes into 60 1 times with a remainder of 14.
The next digit of our result is 1. 
Result so far: 18878.391
Deduct 46 from 60 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
46 can be fit into 140 3 times, resulting in a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 18878.3913
The remainder is 2 after subtracting 138 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
When dividing 20 by 46, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 18878.3913
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
46 goes into 200 4 times with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 18878.391304
The remainder is 16 after subtracting 184 from 200.
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 13:
46 goes into 160 3 times with a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 18878.3913043
Subtracting 138 from 160 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 14:
220 divided by 46 is 4 with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 18878.39130434
Subtracting 184 from 220 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 18878.39130434, with a leftover of 3.6e-08.
