71212108 ÷ 689 
Our goal is to divide 71212108 by 689.

Going ahead to step 1:
The number 689 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 689

Going ahead to step 2:
689 can be fit into 71 0 times, resulting in a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Take the next digit (2) from the dividend and append it to 71, then repeat: 712 / 689

Going ahead to step 3:
If we divide 712 by 689, we get 1 and a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 23 after subtracting 689 from 712.
Bring next digit (1) of the dividend behind the 23 and repeat the process: 231 / 689

Moving on to step 4:
231 divided by 689 is 0 with a remainder of 231.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 231 and we're left with 231.
Include the next digit (2) from the dividend after 231, then repeat: 2312 / 689

Let's proceed to step 5:
The number 689 fits into 2312 3 times, leaving a remainder of 245.
Put 3 as the next digit of the answer. 
Result so far: 103.0
Subtract 2067 from 2312 to get 245.
Append the next digit (1) from the dividend to 245 and continue with: 2451 / 689

Let's proceed to step 6:
2451 divided by 689 is 3 with a remainder of 384.
The next digit of our result is 3. 
Result so far: 1033.0
Deduct 2067 from 2451 and we're left with 384.
Append the next digit (0) from the dividend to 384 and continue with: 3840 / 689

Going ahead to step 7:
When dividing 3840 by 689, we get 5 with a remainder of 395.
Put 5 as the next digit of the answer. 
Result so far: 10335.0
If we subtract 3445 from 3840, we get 395.
Fetch the next digit (8) from the dividend, attach it to 395 and continue: 3958 / 689

Step 8:
If we divide 3958 by 689, we get 5 and a remainder of 513.
Write down 5 as next digit of the result. 
Result so far: 103355.0
If we take 3445 away from 3958, we end up with 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

On to step 9:
689 can be fit into 5130 7 times, resulting in a remainder of 307.
Write down 7 as next digit of the result. 
Result so far: 103355.7
Subtract 4823 from 5130 to get 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Let's proceed to step 10:
The number 689 fits into 3070 4 times, leaving a remainder of 314.
Record the quotient 4 as the next digit in the result. 
Result so far: 103355.74
Subtracting 2756 from 3070 leaves us with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Moving on to step 11:
689 can be fit into 3140 4 times, resulting in a remainder of 384.
Put 4 as the next digit of the answer. 
Result so far: 103355.744
Subtract 2756 from 3140 to get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

The final result is 103355.744 with a remainder of 0.0384.
