Let's divide 443857 by 10
We're looking to find how many times 10 goes into 443857.

Let's proceed to step 1:
When dividing 4 by 10, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 10

Let's proceed to step 2:
44 divided by 10 is 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 4.0
If we take 40 away from 44, we end up with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 10

Moving on to step 3:
The number 10 fits into 43 4 times, leaving a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
The remainder is 3 after subtracting 40 from 43.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 10

Step 4:
When dividing 38 by 10, we get 3 with a remainder of 8.
The next digit of our result is 3. 
Result so far: 443.0
If we subtract 30 from 38, we get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 10

Going ahead to step 5:
10 can be fit into 85 8 times, resulting in a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 4438.0
Deduct 80 from 85 and we're left with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 10

Advancing to step 6:
57 divided by 10 is 5 with a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 44385.0
The remainder is 7 after subtracting 50 from 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
10 can be fit into 70 7 times, resulting in a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 44385.7
Deduct 70 from 70 and we're left 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.

Moving on to step 8:
0 divided by 10 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 44385.7
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 9:
10 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 44385.7
Deduct 0 from 0 and we're left 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 44385.7, with a leftover of 0.0.
