We look at the division of 17788361 by 875 
We want to figure out the number of times 17788361 can be divided by 875.

Let's proceed to step 1:
875 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 875

On to step 2:
875 goes into 17 0 times with a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 875

Let's proceed to step 3:
875 can be fit into 177 0 times, resulting in a remainder of 177.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 177 to get 177.
Grab the next digit (8) from the dividend, add it to 177, then carry on: 1778 / 875

Going ahead to step 4:
1778 divided by 875 is 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 1750 from 1778 to get 28.
Fetch the next digit (8) from the dividend, attach it to 28 and continue: 288 / 875

On to step 5:
If we divide 288 by 875, we get 0 and a remainder of 288.
The next digit of our result is 0. 
Result so far: 20.0
If we subtract 0 from 288, we get 288.
Include the next digit (3) from the dividend after 288, then repeat: 2883 / 875

Let's proceed to step 6:
875 can be fit into 2883 3 times, resulting in a remainder of 258.
The next digit of our result is 3. 
Result so far: 203.0
If we take 2625 away from 2883, we end up with 258.
Append the next digit (6) from the dividend to 258 and continue with: 2586 / 875

Going ahead to step 7:
875 can be fit into 2586 2 times, resulting in a remainder of 836.
Write down 2 as next digit of the result. 
Result so far: 2032.0
Subtracting 1750 from 2586 leaves us with 836.
Grab the next digit (1) from the dividend, add it to 836, then carry on: 8361 / 875

Let's proceed to step 8:
The number 875 fits into 8361 9 times, leaving a remainder of 486.
Use 9 as the next digit of our solution. 
Result so far: 20329.0
If we take 7875 away from 8361, we end up with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

On to step 9:
The number 875 fits into 4860 5 times, leaving a remainder of 485.
Use 5 as the next digit of our solution. 
Result so far: 20329.5
Subtract 4375 from 4860 to get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Advancing to step 10:
When dividing 4850 by 875, we get 5 with a remainder of 475.
Record the quotient 5 as the next digit in the result. 
Result so far: 20329.55
The remainder is 475 after subtracting 4375 from 4850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

The final result is 20329.55 with a remainder of 0.475.
