We're dividing 690794 by 45 
We want to figure out the number of times 690794 can be divided by 45.

Step 1:
If we divide 6 by 45, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 45

Advancing to step 2:
When dividing 69 by 45, we get 1 with a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 24 after subtracting 45 from 69.
Include the next digit (0) from the dividend after 24, then repeat: 240 / 45

Let's proceed to step 3:
The number 45 fits into 240 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we take 225 away from 240, we end up with 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 45

Going ahead to step 4:
When dividing 157 by 45, we get 3 with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 153.0
The remainder is 22 after subtracting 135 from 157.
Include the next digit (9) from the dividend after 22, then repeat: 229 / 45

Advancing to step 5:
The number 45 fits into 229 5 times, leaving a remainder of 4.
The next digit of our result is 5. 
Result so far: 1535.0
Subtract 225 from 229 to get 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 45

Moving on to step 6:
If we divide 44 by 45, we get 0 and a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 15350.0
Subtract 0 from 44 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 7:
If we divide 440 by 45, we get 9 and a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 15350.9
The remainder is 35 after subtracting 405 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 8:
When dividing 350 by 45, we get 7 with a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 15350.97
Deduct 315 from 350 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
45 goes into 350 7 times with a remainder of 35.
The number 7 becomes the next digit in our result. 
Result so far: 15350.977
Subtract 315 from 350 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 15350.977, with a leftover of 0.0035.
