869100 ÷ 35 
Our goal is to divide 869100 by 35.

Going ahead to step 1:
If we divide 8 by 35, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 35

Advancing to step 2:
35 goes into 86 2 times with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 16 after subtracting 70 from 86.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 35

Step 3:
35 goes into 169 4 times with a remainder of 29.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Subtract 140 from 169 to get 29.
Grab the next digit (1) from the dividend, add it to 29, then carry on: 291 / 35

Advancing to step 4:
35 can be fit into 291 8 times, resulting in a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 248.0
Deduct 280 from 291 and we're left with 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 35

Step 5:
The number 35 fits into 110 3 times, leaving a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 2483.0
If we subtract 105 from 110, we get 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 35

Moving on to step 6:
50 divided by 35 is 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 24831.0
If we take 35 away from 50, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
35 can be fit into 150 4 times, resulting in a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 24831.4
The remainder is 10 after subtracting 140 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
100 divided by 35 is 2 with a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 24831.42
The remainder is 30 after subtracting 70 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
The number 35 fits into 300 8 times, leaving a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 24831.428
Subtracting 280 from 300 leaves us 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.

Advancing to step 10:
If we divide 200 by 35, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 24831.4285
The remainder is 25 after subtracting 175 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 11:
35 goes into 250 7 times with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 24831.42857
Subtracting 245 from 250 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 12:
35 goes into 50 1 times with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 24831.428571
If we subtract 35 from 50, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 13:
35 goes into 150 4 times with a remainder of 10.
The next digit of our result is 4. 
Result so far: 24831.4285714
The remainder is 10 after subtracting 140 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
35 goes into 100 2 times with a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 24831.42857142
Subtracting 70 from 100 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 24831.42857142, with a leftover of 3e-08.
