We look at the division of 16891117 by 45 
Our goal is to divide 16891117 by 45.

Going ahead to step 1:
45 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 45

Going ahead to step 2:
The number 45 fits into 16 0 times, leaving a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 45

Advancing to step 3:
45 goes into 168 3 times with a remainder of 33.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 33 after subtracting 135 from 168.
Append the next digit (9) from the dividend to 33 and continue with: 339 / 45

Advancing to step 4:
If we divide 339 by 45, we get 7 and a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 37.0
The remainder is 24 after subtracting 315 from 339.
Bring next digit (1) of the dividend behind the 24 and repeat the process: 241 / 45

On to step 5:
241 divided by 45 is 5 with a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 375.0
If we take 225 away from 241, we end up with 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 45

Let's proceed to step 6:
45 can be fit into 161 3 times, resulting in a remainder of 26.
The next digit of our result is 3. 
Result so far: 3753.0
Deduct 135 from 161 and we're left with 26.
Grab the next digit (1) from the dividend, add it to 26, then carry on: 261 / 45

Advancing to step 7:
261 divided by 45 is 5 with a remainder of 36.
Record the quotient 5 as the next digit in the result. 
Result so far: 37535.0
Subtract 225 from 261 to get 36.
Take the next digit (7) from the dividend and append it to 36, then repeat: 367 / 45

Let's proceed to step 8:
45 can be fit into 367 8 times, resulting in a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 375358.0
Subtracting 360 from 367 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 9:
If we divide 70 by 45, we get 1 and a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 375358.1
Deduct 45 from 70 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
When dividing 250 by 45, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 375358.15
Subtracting 225 from 250 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 11:
If we divide 250 by 45, we get 5 and a remainder of 25.
The next digit of our result is 5. 
Result so far: 375358.155
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 375358.155 and a remainder of 0.0025.
