690938 ÷ 45 
We want to divide 690938 by 45.

Going ahead to step 1:
45 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 45

Let's proceed to step 2:
45 can be fit into 69 1 times, resulting in a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 45 from 69, we get 24.
Bring next digit (0) of the dividend behind the 24 and repeat the process: 240 / 45

Going ahead to step 3:
The number 45 fits into 240 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we subtract 225 from 240, we get 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 45

Moving on to step 4:
The number 45 fits into 159 3 times, leaving a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 153.0
If we subtract 135 from 159, we get 24.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 45

Going ahead to step 5:
The number 45 fits into 243 5 times, leaving a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 1535.0
If we subtract 225 from 243, we get 18.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 45

Going ahead to step 6:
When dividing 188 by 45, we get 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 15354.0
The remainder is 8 after subtracting 180 from 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
If we divide 80 by 45, we get 1 and a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 15354.1
Deduct 45 from 80 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 8:
350 divided by 45 is 7 with a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 15354.17
The remainder is 35 after subtracting 315 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 9:
When dividing 350 by 45, we get 7 with a remainder of 35.
The next digit of our result is 7. 
Result so far: 15354.177
If we take 315 away from 350, we end up 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.

The quotient of the division is 15354.177, and the remainder is 0.0035.
