Let's divide 78162573 by 803
We want to figure out the number of times 78162573 can be divided by 803.

Going ahead to step 1:
7 divided by 803 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 803

Moving on to step 2:
When dividing 78 by 803, we get 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Fetch the next digit (1) from the dividend, attach it to 78 and continue: 781 / 803

Step 3:
The number 803 fits into 781 0 times, leaving a remainder of 781.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 781, we get 781.
Grab the next digit (6) from the dividend, add it to 781, then carry on: 7816 / 803

Going ahead to step 4:
803 can be fit into 7816 9 times, resulting in a remainder of 589.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 589 after subtracting 7227 from 7816.
Take the next digit (2) from the dividend and append it to 589, then repeat: 5892 / 803

Advancing to step 5:
If we divide 5892 by 803, we get 7 and a remainder of 271.
Write down 7 as next digit of the result. 
Result so far: 97.0
The remainder is 271 after subtracting 5621 from 5892.
Include the next digit (5) from the dividend after 271, then repeat: 2715 / 803

Let's proceed to step 6:
When dividing 2715 by 803, we get 3 with a remainder of 306.
Put 3 as the next digit of the answer. 
Result so far: 973.0
Deduct 2409 from 2715 and we're left with 306.
Bring next digit (7) of the dividend behind the 306 and repeat the process: 3067 / 803

Moving on to step 7:
803 can be fit into 3067 3 times, resulting in a remainder of 658.
Record the quotient 3 as the next digit in the result. 
Result so far: 9733.0
Subtract 2409 from 3067 to get 658.
Grab the next digit (3) from the dividend, add it to 658, then carry on: 6583 / 803

Let's proceed to step 8:
6583 divided by 803 is 8 with a remainder of 159.
Put 8 as the next digit of the answer. 
Result so far: 97338.0
The remainder is 159 after subtracting 6424 from 6583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Advancing to step 9:
When dividing 1590 by 803, we get 1 with a remainder of 787.
Record the quotient 1 as the next digit in the result. 
Result so far: 97338.1
If we subtract 803 from 1590, we get 787.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7870, and continue the process.

Advancing to step 10:
When dividing 7870 by 803, we get 9 with a remainder of 643.
The next digit of our result is 9. 
Result so far: 97338.19
Deduct 7227 from 7870 and we're left with 643.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6430, and continue the process.

Step 11:
803 goes into 6430 8 times with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 97338.198
If we subtract 6424 from 6430, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
If we divide 60 by 803, we get 0 and a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 97338.198
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 13:
803 can be fit into 600 0 times, resulting in a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 97338.198
If we subtract 0 from 600, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Our division results in 97338.198 with a remaining 0.0006.
