We're dividing 15941498 by 800 
We're looking to find how many times 800 goes into 15941498.

Let's proceed to step 1:
When dividing 1 by 800, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 800

Going ahead to step 2:
The number 800 fits into 15 0 times, leaving a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 800

Step 3:
159 divided by 800 is 0 with a remainder of 159.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 159 leaves us with 159.
Take the next digit (4) from the dividend and append it to 159, then repeat: 1594 / 800

Step 4:
800 can be fit into 1594 1 times, resulting in a remainder of 794.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 800 from 1594 to get 794.
Bring next digit (1) of the dividend behind the 794 and repeat the process: 7941 / 800

Let's proceed to step 5:
800 can be fit into 7941 9 times, resulting in a remainder of 741.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we subtract 7200 from 7941, we get 741.
Include the next digit (4) from the dividend after 741, then repeat: 7414 / 800

Let's proceed to step 6:
The number 800 fits into 7414 9 times, leaving a remainder of 214.
The next digit of our result is 9. 
Result so far: 199.0
If we take 7200 away from 7414, we end up with 214.
Take the next digit (9) from the dividend and append it to 214, then repeat: 2149 / 800

Let's proceed to step 7:
If we divide 2149 by 800, we get 2 and a remainder of 549.
Write down 2 as next digit of the result. 
Result so far: 1992.0
Deduct 1600 from 2149 and we're left with 549.
Grab the next digit (8) from the dividend, add it to 549, then carry on: 5498 / 800

Going ahead to step 8:
800 can be fit into 5498 6 times, resulting in a remainder of 698.
Put 6 as the next digit of the answer. 
Result so far: 19926.0
Subtract 4800 from 5498 to get 698.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

Step 9:
800 goes into 6980 8 times with a remainder of 580.
The number 8 becomes the next digit in our result. 
Result so far: 19926.8
Subtracting 6400 from 6980 leaves us with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Advancing to step 10:
800 can be fit into 5800 7 times, resulting in a remainder of 200.
Write down 7 as next digit of the result. 
Result so far: 19926.87
If we take 5600 away from 5800, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 11:
The number 800 fits into 2000 2 times, leaving a remainder of 400.
Write down 2 as next digit of the result. 
Result so far: 19926.872
Deduct 1600 from 2000 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 12:
The number 800 fits into 4000 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 19926.8725
Subtract 4000 from 4000 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 13:
The number 800 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 19926.8725
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 14:
If we divide 0 by 800, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 19926.8725
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 19926.8725, with a leftover of 0.0.
