We're dividing 7374099 by 391 
Let's see how many times 391 fits into 7374099.

Let's proceed to step 1:
The number 391 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 391

Let's proceed to step 2:
73 divided by 391 is 0 with a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Bring next digit (7) of the dividend behind the 73 and repeat the process: 737 / 391

Step 3:
If we divide 737 by 391, we get 1 and a remainder of 346.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 391 from 737 to get 346.
Bring next digit (4) of the dividend behind the 346 and repeat the process: 3464 / 391

On to step 4:
If we divide 3464 by 391, we get 8 and a remainder of 336.
The next digit of our result is 8. 
Result so far: 18.0
If we subtract 3128 from 3464, we get 336.
Include the next digit (0) from the dividend after 336, then repeat: 3360 / 391

Moving on to step 5:
391 goes into 3360 8 times with a remainder of 232.
Record the quotient 8 as the next digit in the result. 
Result so far: 188.0
Deduct 3128 from 3360 and we're left with 232.
Fetch the next digit (9) from the dividend, attach it to 232 and continue: 2329 / 391

Advancing to step 6:
391 can be fit into 2329 5 times, resulting in a remainder of 374.
The number 5 becomes the next digit in our result. 
Result so far: 1885.0
If we take 1955 away from 2329, we end up with 374.
Include the next digit (9) from the dividend after 374, then repeat: 3749 / 391

Moving on to step 7:
When dividing 3749 by 391, we get 9 with a remainder of 230.
Write down 9 as next digit of the result. 
Result so far: 18859.0
Subtracting 3519 from 3749 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 8:
The number 391 fits into 2300 5 times, leaving a remainder of 345.
Put 5 as the next digit of the answer. 
Result so far: 18859.5
If we subtract 1955 from 2300, we get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

On to step 9:
The number 391 fits into 3450 8 times, leaving a remainder of 322.
Use 8 as the next digit of our solution. 
Result so far: 18859.58
Deduct 3128 from 3450 and we're left with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Step 10:
The number 391 fits into 3220 8 times, leaving a remainder of 92.
Use 8 as the next digit of our solution. 
Result so far: 18859.588
Subtracting 3128 from 3220 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

The final outcome is 18859.588, with a leftover of 0.0092.
