We're dividing 83161823 by 45 
We want to divide 83161823 by 45.

Step 1:
45 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 45

Going ahead to step 2:
When dividing 83 by 45, we get 1 with a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 45 from 83 and we're left with 38.
Bring next digit (1) of the dividend behind the 38 and repeat the process: 381 / 45

Going ahead to step 3:
45 goes into 381 8 times with a remainder of 21.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 21 after subtracting 360 from 381.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 45

Step 4:
If we divide 216 by 45, we get 4 and a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 184.0
If we take 180 away from 216, we end up with 36.
Take the next digit (1) from the dividend and append it to 36, then repeat: 361 / 45

On to step 5:
The number 45 fits into 361 8 times, leaving a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 1848.0
If we subtract 360 from 361, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 45

On to step 6:
45 can be fit into 18 0 times, resulting in a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 18480.0
Deduct 0 from 18 and we're left with 18.
Include the next digit (2) from the dividend after 18, then repeat: 182 / 45

Advancing to step 7:
45 can be fit into 182 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 184804.0
Subtracting 180 from 182 leaves us with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 45

Moving on to step 8:
When dividing 23 by 45, we get 0 with a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 1848040.0
Subtracting 0 from 23 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 9:
When dividing 230 by 45, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 1848040.5
Subtract 225 from 230 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
When dividing 50 by 45, we get 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1848040.51
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 11:
The number 45 fits into 50 1 times, leaving a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1848040.511
Subtracting 45 from 50 leaves us 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.

The final result is 1848040.511 with a remainder of 0.0005.
