31567066 ÷ 858 
We want to figure out the number of times 31567066 can be divided by 858.

On to step 1:
When dividing 3 by 858, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 858

Going ahead to step 2:
When dividing 31 by 858, we get 0 with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Include the next digit (5) from the dividend after 31, then repeat: 315 / 858

Advancing to step 3:
315 divided by 858 is 0 with a remainder of 315.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 315, we end up with 315.
Fetch the next digit (6) from the dividend, attach it to 315 and continue: 3156 / 858

On to step 4:
3156 divided by 858 is 3 with a remainder of 582.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 2574 from 3156, we get 582.
Bring next digit (7) of the dividend behind the 582 and repeat the process: 5827 / 858

Moving on to step 5:
When dividing 5827 by 858, we get 6 with a remainder of 679.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
Subtract 5148 from 5827 to get 679.
Fetch the next digit (0) from the dividend, attach it to 679 and continue: 6790 / 858

On to step 6:
If we divide 6790 by 858, we get 7 and a remainder of 784.
The number 7 becomes the next digit in our result. 
Result so far: 367.0
Deduct 6006 from 6790 and we're left with 784.
Include the next digit (6) from the dividend after 784, then repeat: 7846 / 858

Let's proceed to step 7:
7846 divided by 858 is 9 with a remainder of 124.
Put 9 as the next digit of the answer. 
Result so far: 3679.0
Deduct 7722 from 7846 and we're left with 124.
Fetch the next digit (6) from the dividend, attach it to 124 and continue: 1246 / 858

Let's proceed to step 8:
If we divide 1246 by 858, we get 1 and a remainder of 388.
Put 1 as the next digit of the answer. 
Result so far: 36791.0
The remainder is 388 after subtracting 858 from 1246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Moving on to step 9:
The number 858 fits into 3880 4 times, leaving a remainder of 448.
Put 4 as the next digit of the answer. 
Result so far: 36791.4
Subtracting 3432 from 3880 leaves us with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Going ahead to step 10:
858 goes into 4480 5 times with a remainder of 190.
The next digit of our result is 5. 
Result so far: 36791.45
Deduct 4290 from 4480 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 11:
858 goes into 1900 2 times with a remainder of 184.
The number 2 becomes the next digit in our result. 
Result so far: 36791.452
Deduct 1716 from 1900 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 12:
858 can be fit into 1840 2 times, resulting in a remainder of 124.
Use 2 as the next digit of our solution. 
Result so far: 36791.4522
Subtracting 1716 from 1840 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

In conclusion, the division gives 36791.4522 with a balance of 0.00124.
