We divide 79789993 by 45
We want to divide 79789993 by 45.

Let's proceed to step 1:
The number 45 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 45

Step 2:
The number 45 fits into 79 1 times, leaving a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 45 from 79 to get 34.
Fetch the next digit (7) from the dividend, attach it to 34 and continue: 347 / 45

Advancing to step 3:
45 goes into 347 7 times with a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtract 315 from 347 to get 32.
Include the next digit (8) from the dividend after 32, then repeat: 328 / 45

Going ahead to step 4:
When dividing 328 by 45, we get 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 177.0
Subtracting 315 from 328 leaves us with 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 45

On to step 5:
If we divide 139 by 45, we get 3 and a remainder of 4.
The next digit of our result is 3. 
Result so far: 1773.0
The remainder is 4 after subtracting 135 from 139.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 45

Let's proceed to step 6:
When dividing 49 by 45, we get 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 17731.0
Subtract 45 from 49 to get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 45

Let's proceed to step 7:
When dividing 49 by 45, we get 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 177311.0
If we take 45 away from 49, we end up with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 45

Going ahead to step 8:
45 can be fit into 43 0 times, resulting in a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 1773110.0
Subtracting 0 from 43 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 9:
45 goes into 430 9 times with a remainder of 25.
Record the quotient 9 as the next digit in the result. 
Result so far: 1773110.9
Subtracting 405 from 430 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.

Let's proceed 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: 1773110.95
If we subtract 225 from 250, we get 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 11:
When dividing 250 by 45, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 1773110.955
Deduct 225 from 250 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.

Our division results in 1773110.955 with a remaining 0.0025.
