Let's divide 373406 by 15
We want to figure out the number of times 373406 can be divided by 15.

Step 1:
15 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 15

On to step 2:
The number 15 fits into 37 2 times, leaving a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 30 from 37 and we're left with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 15

Advancing to step 3:
When dividing 73 by 15, we get 4 with a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Subtracting 60 from 73 leaves us with 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 15

Going ahead to step 4:
If we divide 134 by 15, we get 8 and a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 248.0
Subtract 120 from 134 to get 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 15

Moving on to step 5:
When dividing 140 by 15, we get 9 with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 2489.0
Deduct 135 from 140 and we're left with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 15

Moving on to step 6:
If we divide 56 by 15, we get 3 and a remainder of 11.
The next digit of our result is 3. 
Result so far: 24893.0
If we subtract 45 from 56, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
15 goes into 110 7 times with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 24893.7
If we subtract 105 from 110, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 24893.73
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
When dividing 50 by 15, we get 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 24893.733
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 24893.733 with a balance of 0.0005.
