187817 divided by 45 
Let's see how many times 45 fits into 187817.

Going ahead to step 1:
45 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 45

Moving on to step 2:
18 divided by 45 is 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Grab the next digit (7) from the dividend, add it to 18, then carry on: 187 / 45

On to step 3:
If we divide 187 by 45, we get 4 and a remainder of 7.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 180 from 187 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 45

Advancing to step 4:
45 can be fit into 78 1 times, resulting in a remainder of 33.
The next digit of our result is 1. 
Result so far: 41.0
If we subtract 45 from 78, we get 33.
Bring next digit (1) of the dividend behind the 33 and repeat the process: 331 / 45

Let's proceed to step 5:
The number 45 fits into 331 7 times, leaving a remainder of 16.
The next digit of our result is 7. 
Result so far: 417.0
Deduct 315 from 331 and we're left with 16.
Append the next digit (7) from the dividend to 16 and continue with: 167 / 45

Step 6:
If we divide 167 by 45, we get 3 and a remainder of 32.
Record the quotient 3 as the next digit in the result. 
Result so far: 4173.0
Deduct 135 from 167 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 7:
45 can be fit into 320 7 times, resulting in a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 4173.7
The remainder is 5 after subtracting 315 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 8:
When dividing 50 by 45, we get 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 4173.71
Deduct 45 from 50 and we're left 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.

Step 9:
The number 45 fits into 50 1 times, leaving a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 4173.711
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 4173.711 and a remainder of 0.0005.
