69980596 ÷ 18 
We want to figure out the number of times 69980596 can be divided by 18.

Advancing to step 1:
6 divided by 18 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 18

On to step 2:
69 divided by 18 is 3 with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 54 from 69 to get 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 18

Advancing to step 3:
18 goes into 159 8 times with a remainder of 15.
The next digit of our result is 8. 
Result so far: 38.0
Deduct 144 from 159 and we're left with 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 18

On to step 4:
18 can be fit into 158 8 times, resulting in a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 388.0
If we subtract 144 from 158, we get 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 18

Going ahead to step 5:
18 goes into 140 7 times with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 3887.0
Subtracting 126 from 140 leaves us with 14.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 18

On to step 6:
145 divided by 18 is 8 with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 38878.0
If we take 144 away from 145, we end up with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 18

On to step 7:
When dividing 19 by 18, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 388781.0
Subtracting 18 from 19 leaves us with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 18

Let's proceed to step 8:
18 can be fit into 16 0 times, resulting in a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 3887810.0
Subtract 0 from 16 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 9:
If we divide 160 by 18, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 3887810.8
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
160 divided by 18 is 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 3887810.88
If we take 144 away from 160, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 3887810.88 with a remaining 0.016.
