We look at the division of 857394 by 46 
Let's see how many times 46 fits into 857394.

Moving on to step 1:
46 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 46

Let's proceed to step 2:
The number 46 fits into 85 1 times, leaving a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 46 from 85 and we're left with 39.
Fetch the next digit (7) from the dividend, attach it to 39 and continue: 397 / 46

On to step 3:
When dividing 397 by 46, we get 8 with a remainder of 29.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Deduct 368 from 397 and we're left with 29.
Bring next digit (3) of the dividend behind the 29 and repeat the process: 293 / 46

Let's proceed to step 4:
46 goes into 293 6 times with a remainder of 17.
Record the quotient 6 as the next digit in the result. 
Result so far: 186.0
The remainder is 17 after subtracting 276 from 293.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 46

Advancing to step 5:
46 goes into 179 3 times with a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 1863.0
If we take 138 away from 179, we end up with 41.
Bring next digit (4) of the dividend behind the 41 and repeat the process: 414 / 46

Advancing to step 6:
46 can be fit into 414 9 times, resulting in a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 18639.0
Subtracting 414 from 414 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
The number 46 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18639.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
46 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 18639.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 18639.0, with a leftover of 0.0.
