Let's divide 81981481 by 688
We want to divide 81981481 by 688.

Step 1:
688 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 688

Moving on to step 2:
The number 688 fits into 81 0 times, leaving a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Append the next digit (9) from the dividend to 81 and continue with: 819 / 688

On to step 3:
688 goes into 819 1 times with a remainder of 131.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 688 from 819 and we're left with 131.
Fetch the next digit (8) from the dividend, attach it to 131 and continue: 1318 / 688

Let's proceed to step 4:
The number 688 fits into 1318 1 times, leaving a remainder of 630.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 688 away from 1318, we end up with 630.
Bring next digit (1) of the dividend behind the 630 and repeat the process: 6301 / 688

Step 5:
688 goes into 6301 9 times with a remainder of 109.
Use 9 as the next digit of our solution. 
Result so far: 119.0
Subtract 6192 from 6301 to get 109.
Append the next digit (4) from the dividend to 109 and continue with: 1094 / 688

Going ahead to step 6:
688 goes into 1094 1 times with a remainder of 406.
Record the quotient 1 as the next digit in the result. 
Result so far: 1191.0
The remainder is 406 after subtracting 688 from 1094.
Bring next digit (8) of the dividend behind the 406 and repeat the process: 4068 / 688

Advancing to step 7:
When dividing 4068 by 688, we get 5 with a remainder of 628.
Write down 5 as next digit of the result. 
Result so far: 11915.0
Deduct 3440 from 4068 and we're left with 628.
Append the next digit (1) from the dividend to 628 and continue with: 6281 / 688

On to step 8:
688 goes into 6281 9 times with a remainder of 89.
The number 9 becomes the next digit in our result. 
Result so far: 119159.0
Deduct 6192 from 6281 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 9:
If we divide 890 by 688, we get 1 and a remainder of 202.
Use 1 as the next digit of our solution. 
Result so far: 119159.1
Deduct 688 from 890 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Advancing to step 10:
When dividing 2020 by 688, we get 2 with a remainder of 644.
Write down 2 as next digit of the result. 
Result so far: 119159.12
Subtracting 1376 from 2020 leaves us with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

On to step 11:
688 goes into 6440 9 times with a remainder of 248.
Record the quotient 9 as the next digit in the result. 
Result so far: 119159.129
The remainder is 248 after subtracting 6192 from 6440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 12:
2480 divided by 688 is 3 with a remainder of 416.
The number 3 becomes the next digit in our result. 
Result so far: 119159.1293
Subtracting 2064 from 2480 leaves us with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

On to step 13:
The number 688 fits into 4160 6 times, leaving a remainder of 32.
The next digit of our result is 6. 
Result so far: 119159.12936
Subtracting 4128 from 4160 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 14:
320 divided by 688 is 0 with a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 119159.12936
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 15:
688 goes into 3200 4 times with a remainder of 448.
Record the quotient 4 as the next digit in the result. 
Result so far: 119159.1293604
Subtracting 2752 from 3200 leaves us with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Advancing to step 16:
688 goes into 4480 6 times with a remainder of 352.
Record the quotient 6 as the next digit in the result. 
Result so far: 119159.12936046
The remainder is 352 after subtracting 4128 from 4480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

After the division, we end up with 119159.12936046 and a remainder of 3.52e-07.
