70837 ÷ 18 
We're looking to find how many times 18 goes into 70837.

Let's proceed to step 1:
If we divide 7 by 18, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 18

Advancing to step 2:
When dividing 70 by 18, we get 3 with a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 54 from 70, we get 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 18

Advancing to step 3:
18 goes into 168 9 times with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 39.0
Deduct 162 from 168 and we're left with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 18

Let's proceed to step 4:
If we divide 63 by 18, we get 3 and a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 393.0
Deduct 54 from 63 and we're left with 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 18

On to step 5:
97 divided by 18 is 5 with a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 3935.0
If we subtract 90 from 97, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 6:
If we divide 70 by 18, we get 3 and a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 3935.3
The remainder is 16 after subtracting 54 from 70.
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 7:
When dividing 160 by 18, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 3935.38
Subtract 144 from 160 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.

Going ahead to step 8:
18 goes into 160 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 3935.388
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.

The final result is 3935.388 with a remainder of 0.0016.
