We look at the division of 74578412 by 100 
Let's see how many times 100 fits into 74578412.

Moving on to step 1:
When dividing 7 by 100, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 100

Moving on to step 2:
100 goes into 74 0 times with a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 74, we end up with 74.
Fetch the next digit (5) from the dividend, attach it to 74 and continue: 745 / 100

Let's proceed to step 3:
If we divide 745 by 100, we get 7 and a remainder of 45.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 700 from 745 to get 45.
Bring next digit (7) of the dividend behind the 45 and repeat the process: 457 / 100

Advancing to step 4:
When dividing 457 by 100, we get 4 with a remainder of 57.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
Subtract 400 from 457 to get 57.
Grab the next digit (8) from the dividend, add it to 57, then carry on: 578 / 100

Advancing to step 5:
100 can be fit into 578 5 times, resulting in a remainder of 78.
The number 5 becomes the next digit in our result. 
Result so far: 745.0
If we subtract 500 from 578, we get 78.
Append the next digit (4) from the dividend to 78 and continue with: 784 / 100

Moving on to step 6:
100 goes into 784 7 times with a remainder of 84.
Write down 7 as next digit of the result. 
Result so far: 7457.0
If we take 700 away from 784, we end up with 84.
Include the next digit (1) from the dividend after 84, then repeat: 841 / 100

Moving on to step 7:
The number 100 fits into 841 8 times, leaving a remainder of 41.
Use 8 as the next digit of our solution. 
Result so far: 74578.0
If we take 800 away from 841, we end up with 41.
Append the next digit (2) from the dividend to 41 and continue with: 412 / 100

Going ahead to step 8:
When dividing 412 by 100, we get 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 745784.0
Subtract 400 from 412 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
100 can be fit into 120 1 times, resulting in a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 745784.1
If we take 100 away from 120, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
The number 100 fits into 200 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 745784.12
If we take 200 away from 200, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
The number 100 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 745784.12
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
100 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 745784.12
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 745784.12, with a leftover of 0.0.
