689917 ÷ 45 
Let's see how many times 45 fits into 689917.

Advancing to step 1:
6 divided by 45 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 45

Let's proceed to step 2:
When dividing 68 by 45, we get 1 with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 45 from 68 leaves us with 23.
Bring next digit (9) of the dividend behind the 23 and repeat the process: 239 / 45

Step 3:
239 divided by 45 is 5 with a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 225 from 239, we get 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 45

Advancing to step 4:
The number 45 fits into 149 3 times, leaving a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 153.0
If we take 135 away from 149, we end up with 14.
Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 45

Moving on to step 5:
45 can be fit into 141 3 times, resulting in a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 1533.0
Deduct 135 from 141 and we're left with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 45

Going ahead to step 6:
If we divide 67 by 45, we get 1 and a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 15331.0
Subtract 45 from 67 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
If we divide 220 by 45, we get 4 and a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 15331.4
If we subtract 180 from 220, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
If we divide 400 by 45, we get 8 and a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 15331.48
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
The number 45 fits into 400 8 times, leaving a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 15331.488
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 15331.488, with a leftover of 0.004.
