We look at the division of 3169410 by 858 
Let's see how many times 858 fits into 3169410.

Moving on to step 1:
3 divided by 858 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 858

Let's proceed to step 2:
858 goes into 31 0 times with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Take the next digit (6) from the dividend and append it to 31, then repeat: 316 / 858

On to step 3:
316 divided by 858 is 0 with a remainder of 316.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 316 after subtracting 0 from 316.
Include the next digit (9) from the dividend after 316, then repeat: 3169 / 858

Moving on to step 4:
The number 858 fits into 3169 3 times, leaving a remainder of 595.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 595 after subtracting 2574 from 3169.
Append the next digit (4) from the dividend to 595 and continue with: 5954 / 858

Moving on to step 5:
858 goes into 5954 6 times with a remainder of 806.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
If we take 5148 away from 5954, we end up with 806.
Include the next digit (1) from the dividend after 806, then repeat: 8061 / 858

Going ahead to step 6:
858 can be fit into 8061 9 times, resulting in a remainder of 339.
Record the quotient 9 as the next digit in the result. 
Result so far: 369.0
Subtracting 7722 from 8061 leaves us with 339.
Take the next digit (0) from the dividend and append it to 339, then repeat: 3390 / 858

On to step 7:
3390 divided by 858 is 3 with a remainder of 816.
The number 3 becomes the next digit in our result. 
Result so far: 3693.0
If we take 2574 away from 3390, we end up with 816.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

Moving on to step 8:
The number 858 fits into 8160 9 times, leaving a remainder of 438.
Write down 9 as next digit of the result. 
Result so far: 3693.9
Subtract 7722 from 8160 to get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Moving on to step 9:
858 goes into 4380 5 times with a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 3693.95
Subtract 4290 from 4380 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 10:
When dividing 900 by 858, we get 1 with a remainder of 42.
The next digit of our result is 1. 
Result so far: 3693.951
If we take 858 away from 900, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 11:
420 divided by 858 is 0 with a remainder of 420.
Use 0 as the next digit of our solution. 
Result so far: 3693.951
Subtracting 0 from 420 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 12:
858 goes into 4200 4 times with a remainder of 768.
The number 4 becomes the next digit in our result. 
Result so far: 3693.95104
Subtract 3432 from 4200 to get 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Moving on to step 13:
The number 858 fits into 7680 8 times, leaving a remainder of 816.
Record the quotient 8 as the next digit in the result. 
Result so far: 3693.951048
If we take 6864 away from 7680, we end up with 816.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

Let's proceed to step 14:
If we divide 8160 by 858, we get 9 and a remainder of 438.
The number 9 becomes the next digit in our result. 
Result so far: 3693.9510489
Subtracting 7722 from 8160 leaves us with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Moving on to step 15:
858 goes into 4380 5 times with a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 3693.95104895
Deduct 4290 from 4380 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

After the division, we end up with 3693.95104895 and a remainder of 9e-08.
