858402 divided by 83 
We're looking to find how many times 83 goes into 858402.

Step 1:
When dividing 8 by 83, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 83

Advancing to step 2:
85 divided by 83 is 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 83 away from 85, we end up with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 83

Moving on to step 3:
83 goes into 28 0 times with a remainder of 28.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 28, we end up with 28.
Include the next digit (4) from the dividend after 28, then repeat: 284 / 83

Going ahead to step 4:
The number 83 fits into 284 3 times, leaving a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
Deduct 249 from 284 and we're left with 35.
Take the next digit (0) from the dividend and append it to 35, then repeat: 350 / 83

Step 5:
83 goes into 350 4 times with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 1034.0
If we subtract 332 from 350, we get 18.
Include the next digit (2) from the dividend after 18, then repeat: 182 / 83

Let's proceed to step 6:
83 goes into 182 2 times with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 10342.0
If we subtract 166 from 182, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
The number 83 fits into 160 1 times, leaving a remainder of 77.
Record the quotient 1 as the next digit in the result. 
Result so far: 10342.1
If we subtract 83 from 160, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 8:
The number 83 fits into 770 9 times, leaving a remainder of 23.
The next digit of our result is 9. 
Result so far: 10342.19
Deduct 747 from 770 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 9:
230 divided by 83 is 2 with a remainder of 64.
The next digit of our result is 2. 
Result so far: 10342.192
Deduct 166 from 230 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 10:
The number 83 fits into 640 7 times, leaving a remainder of 59.
The next digit of our result is 7. 
Result so far: 10342.1927
If we subtract 581 from 640, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 11:
590 divided by 83 is 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 10342.19277
Subtracting 581 from 590 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

In conclusion, the division gives 10342.19277 with a balance of 9e-06.
