We're dividing 8786170 by 349 
We want to figure out the number of times 8786170 can be divided by 349.

Moving on to step 1:
349 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 349

On to step 2:
349 goes into 87 0 times with a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Append the next digit (8) from the dividend to 87 and continue with: 878 / 349

Step 3:
349 goes into 878 2 times with a remainder of 180.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 698 away from 878, we end up with 180.
Fetch the next digit (6) from the dividend, attach it to 180 and continue: 1806 / 349

Advancing to step 4:
349 can be fit into 1806 5 times, resulting in a remainder of 61.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we take 1745 away from 1806, we end up with 61.
Take the next digit (1) from the dividend and append it to 61, then repeat: 611 / 349

Going ahead to step 5:
The number 349 fits into 611 1 times, leaving a remainder of 262.
Put 1 as the next digit of the answer. 
Result so far: 251.0
The remainder is 262 after subtracting 349 from 611.
Take the next digit (7) from the dividend and append it to 262, then repeat: 2627 / 349

Advancing to step 6:
When dividing 2627 by 349, we get 7 with a remainder of 184.
The next digit of our result is 7. 
Result so far: 2517.0
If we take 2443 away from 2627, we end up with 184.
Append the next digit (0) from the dividend to 184 and continue with: 1840 / 349

Step 7:
When dividing 1840 by 349, we get 5 with a remainder of 95.
The number 5 becomes the next digit in our result. 
Result so far: 25175.0
If we subtract 1745 from 1840, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 8:
349 goes into 950 2 times with a remainder of 252.
The number 2 becomes the next digit in our result. 
Result so far: 25175.2
The remainder is 252 after subtracting 698 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 9:
The number 349 fits into 2520 7 times, leaving a remainder of 77.
Use 7 as the next digit of our solution. 
Result so far: 25175.27
If we subtract 2443 from 2520, 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.

Going ahead to step 10:
When dividing 770 by 349, we get 2 with a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 25175.272
If we take 698 away from 770, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 11:
When dividing 720 by 349, we get 2 with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 25175.2722
Deduct 698 from 720 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 25175.2722, with a leftover of 0.00022.
