861885 divided by 5 
We're looking to find how many times 5 goes into 861885.

Going ahead to step 1:
If we divide 8 by 5, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 5 from 8 leaves us with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 5

Going ahead to step 2:
5 can be fit into 36 7 times, resulting in a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtract 35 from 36 to get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 5

Step 3:
5 can be fit into 11 2 times, resulting in a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 172.0
If we subtract 10 from 11, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 5

Step 4:
5 can be fit into 18 3 times, resulting in a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 1723.0
If we take 15 away from 18, we end up with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 5

Moving on to step 5:
5 can be fit into 38 7 times, resulting in a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 17237.0
If we take 35 away from 38, we end up with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 5

Advancing to step 6:
5 can be fit into 35 7 times, resulting in a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 172377.0
Subtract 35 from 35 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
When dividing 0 by 5, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 172377.0
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.

On to step 8:
5 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 172377.0
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 172377.0, with a leftover of 0.0.
