We're dividing 13188073 by 862 
We're looking to find how many times 862 goes into 13188073.

Let's proceed to step 1:
1 divided by 862 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 862

Advancing to step 2:
When dividing 13 by 862, we get 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 862

Moving on to step 3:
131 divided by 862 is 0 with a remainder of 131.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 131, we end up with 131.
Take the next digit (8) from the dividend and append it to 131, then repeat: 1318 / 862

Going ahead to step 4:
1318 divided by 862 is 1 with a remainder of 456.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 862 from 1318, we get 456.
Take the next digit (8) from the dividend and append it to 456, then repeat: 4568 / 862

Moving on to step 5:
4568 divided by 862 is 5 with a remainder of 258.
The next digit of our result is 5. 
Result so far: 15.0
Deduct 4310 from 4568 and we're left with 258.
Take the next digit (0) from the dividend and append it to 258, then repeat: 2580 / 862

Moving on to step 6:
If we divide 2580 by 862, we get 2 and a remainder of 856.
Record the quotient 2 as the next digit in the result. 
Result so far: 152.0
Deduct 1724 from 2580 and we're left with 856.
Fetch the next digit (7) from the dividend, attach it to 856 and continue: 8567 / 862

Advancing to step 7:
862 can be fit into 8567 9 times, resulting in a remainder of 809.
Use 9 as the next digit of our solution. 
Result so far: 1529.0
Subtracting 7758 from 8567 leaves us with 809.
Include the next digit (3) from the dividend after 809, then repeat: 8093 / 862

Step 8:
If we divide 8093 by 862, we get 9 and a remainder of 335.
Put 9 as the next digit of the answer. 
Result so far: 15299.0
Deduct 7758 from 8093 and we're left with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Advancing to step 9:
3350 divided by 862 is 3 with a remainder of 764.
The next digit of our result is 3. 
Result so far: 15299.3
If we subtract 2586 from 3350, we get 764.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

Going ahead to step 10:
862 goes into 7640 8 times with a remainder of 744.
Use 8 as the next digit of our solution. 
Result so far: 15299.38
If we take 6896 away from 7640, we end up with 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Step 11:
862 can be fit into 7440 8 times, resulting in a remainder of 544.
The next digit of our result is 8. 
Result so far: 15299.388
If we take 6896 away from 7440, we end up with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

The final outcome is 15299.388, with a leftover of 0.0544.
