Let's divide 83970829 by 858
We're looking to find how many times 858 goes into 83970829.

Let's proceed to step 1:
858 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 858

Moving on to step 2:
If we divide 83 by 858, we get 0 and a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 83, we end up with 83.
Grab the next digit (9) from the dividend, add it to 83, then carry on: 839 / 858

Advancing to step 3:
If we divide 839 by 858, we get 0 and a remainder of 839.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 839 leaves us with 839.
Grab the next digit (7) from the dividend, add it to 839, then carry on: 8397 / 858

Step 4:
858 can be fit into 8397 9 times, resulting in a remainder of 675.
The next digit of our result is 9. 
Result so far: 9.0
If we take 7722 away from 8397, we end up with 675.
Append the next digit (0) from the dividend to 675 and continue with: 6750 / 858

Going ahead to step 5:
6750 divided by 858 is 7 with a remainder of 744.
The next digit of our result is 7. 
Result so far: 97.0
If we take 6006 away from 6750, we end up with 744.
Include the next digit (8) from the dividend after 744, then repeat: 7448 / 858

Going ahead to step 6:
When dividing 7448 by 858, we get 8 with a remainder of 584.
The next digit of our result is 8. 
Result so far: 978.0
Deduct 6864 from 7448 and we're left with 584.
Take the next digit (2) from the dividend and append it to 584, then repeat: 5842 / 858

Advancing to step 7:
858 can be fit into 5842 6 times, resulting in a remainder of 694.
Use 6 as the next digit of our solution. 
Result so far: 9786.0
Subtracting 5148 from 5842 leaves us with 694.
Take the next digit (9) from the dividend and append it to 694, then repeat: 6949 / 858

Going ahead to step 8:
858 can be fit into 6949 8 times, resulting in a remainder of 85.
The number 8 becomes the next digit in our result. 
Result so far: 97868.0
Subtract 6864 from 6949 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 9:
858 can be fit into 850 0 times, resulting in a remainder of 850.
Write down 0 as next digit of the result. 
Result so far: 97868.0
Subtract 0 from 850 to get 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8500, and continue the process.

Step 10:
The number 858 fits into 8500 9 times, leaving a remainder of 778.
Use 9 as the next digit of our solution. 
Result so far: 97868.09
If we take 7722 away from 8500, we end up with 778.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7780, and continue the process.

Step 11:
When dividing 7780 by 858, we get 9 with a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 97868.099
Subtracting 7722 from 7780 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

After the division, we end up with 97868.099 and a remainder of 0.0058.
