751834 divided by 45 
We want to figure out the number of times 751834 can be divided by 45.

Advancing to step 1:
45 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 45

Advancing to step 2:
If we divide 75 by 45, we get 1 and a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 45 from 75 and we're left with 30.
Grab the next digit (1) from the dividend, add it to 30, then carry on: 301 / 45

Moving on to step 3:
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: 16.0
If we take 270 away from 301, we end up with 31.
Take the next digit (8) from the dividend and append it to 31, then repeat: 318 / 45

On to step 4:
45 can be fit into 318 7 times, resulting in a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 167.0
Subtract 315 from 318 to get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 45

Advancing to step 5:
If we divide 33 by 45, we get 0 and a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 1670.0
Subtracting 0 from 33 leaves us with 33.
Grab the next digit (4) from the dividend, add it to 33, then carry on: 334 / 45

Going ahead to step 6:
When dividing 334 by 45, we get 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 16707.0
If we take 315 away from 334, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
If we divide 190 by 45, we get 4 and a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 16707.4
Subtracting 180 from 190 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
45 goes into 100 2 times with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 16707.42
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
When dividing 100 by 45, we get 2 with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 16707.422
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 16707.422 with a remainder of 0.001.
