345112 ÷ 45 
Let's see how many times 45 fits into 345112.

On to step 1:
45 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 45

Let's proceed to step 2:
34 divided by 45 is 0 with a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Bring next digit (5) of the dividend behind the 34 and repeat the process: 345 / 45

Let's proceed to step 3:
The number 45 fits into 345 7 times, leaving a remainder of 30.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 315 from 345 to get 30.
Grab the next digit (1) from the dividend, add it to 30, then carry on: 301 / 45

Let's proceed to step 4:
If we divide 301 by 45, we get 6 and a remainder of 31.
Write down 6 as next digit of the result. 
Result so far: 76.0
Deduct 270 from 301 and we're left with 31.
Include the next digit (1) from the dividend after 31, then repeat: 311 / 45

Moving on to step 5:
311 divided by 45 is 6 with a remainder of 41.
The number 6 becomes the next digit in our result. 
Result so far: 766.0
The remainder is 41 after subtracting 270 from 311.
Bring next digit (2) of the dividend behind the 41 and repeat the process: 412 / 45

Let's proceed to step 6:
When dividing 412 by 45, we get 9 with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 7669.0
Subtract 405 from 412 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
70 divided by 45 is 1 with a remainder of 25.
The next digit of our result is 1. 
Result so far: 7669.1
If we subtract 45 from 70, 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.

Moving on to step 8:
250 divided by 45 is 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 7669.15
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.

Advancing to step 9:
If we divide 250 by 45, we get 5 and a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 7669.155
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.

The final result is 7669.155 with a remainder of 0.0025.
