688131 ÷ 35 
We want to divide 688131 by 35.

Going ahead to step 1:
35 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 35

Going ahead to step 2:
68 divided by 35 is 1 with a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 35 from 68 to get 33.
Grab the next digit (8) from the dividend, add it to 33, then carry on: 338 / 35

Moving on to step 3:
35 can be fit into 338 9 times, resulting in a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Deduct 315 from 338 and we're left with 23.
Take the next digit (1) from the dividend and append it to 23, then repeat: 231 / 35

Advancing to step 4:
35 goes into 231 6 times with a remainder of 21.
The number 6 becomes the next digit in our result. 
Result so far: 196.0
If we subtract 210 from 231, we get 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 35

Step 5:
35 goes into 213 6 times with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 1966.0
The remainder is 3 after subtracting 210 from 213.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 35

Going ahead to step 6:
31 divided by 35 is 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 19660.0
If we take 0 away from 31, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
35 goes into 310 8 times with a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 19660.8
If we subtract 280 from 310, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
35 goes into 300 8 times with a remainder of 20.
The next digit of our result is 8. 
Result so far: 19660.88
Deduct 280 from 300 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 19660.88 with a remainder of 0.02.
