858447 ÷ 39 
We're looking to find how many times 39 goes into 858447.

Step 1:
39 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 39

Moving on to step 2:
39 can be fit into 85 2 times, resulting in a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 78 from 85, we get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 39

Moving on to step 3:
When dividing 78 by 39, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Subtracting 78 from 78 leaves us with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 39

Step 4:
When dividing 4 by 39, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 220.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 39

Let's proceed to step 5:
39 goes into 44 1 times with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 2201.0
Subtracting 39 from 44 leaves us with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 39

Step 6:
39 can be fit into 57 1 times, resulting in a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 22011.0
The remainder is 18 after subtracting 39 from 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
39 goes into 180 4 times with a remainder of 24.
The next digit of our result is 4. 
Result so far: 22011.4
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 8:
The number 39 fits into 240 6 times, leaving a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 22011.46
If we take 234 away from 240, we end up 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.

Moving on to step 9:
60 divided by 39 is 1 with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 22011.461
The remainder is 21 after subtracting 39 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 10:
When dividing 210 by 39, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 22011.4615
Subtract 195 from 210 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
The number 39 fits into 150 3 times, leaving a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 22011.46153
Deduct 117 from 150 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 12:
39 goes into 330 8 times with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 22011.461538
Subtract 312 from 330 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 13:
180 divided by 39 is 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 22011.4615384
Deduct 156 from 180 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 14:
If we divide 240 by 39, we get 6 and a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 22011.46153846
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 22011.46153846, with a leftover of 6e-09.
