We look at the division of 81386670 by 136 
Our goal is to divide 81386670 by 136.

Let's proceed to step 1:
8 divided by 136 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 136

Going ahead to step 2:
When dividing 81 by 136, we get 0 with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Grab the next digit (3) from the dividend, add it to 81, then carry on: 813 / 136

Moving on to step 3:
The number 136 fits into 813 5 times, leaving a remainder of 133.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 680 from 813, we get 133.
Bring next digit (8) of the dividend behind the 133 and repeat the process: 1338 / 136

Let's proceed to step 4:
The number 136 fits into 1338 9 times, leaving a remainder of 114.
The next digit of our result is 9. 
Result so far: 59.0
If we take 1224 away from 1338, we end up with 114.
Include the next digit (6) from the dividend after 114, then repeat: 1146 / 136

Let's proceed to step 5:
If we divide 1146 by 136, we get 8 and a remainder of 58.
Record the quotient 8 as the next digit in the result. 
Result so far: 598.0
Deduct 1088 from 1146 and we're left with 58.
Bring next digit (6) of the dividend behind the 58 and repeat the process: 586 / 136

Step 6:
136 can be fit into 586 4 times, resulting in a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 5984.0
Subtracting 544 from 586 leaves us with 42.
Include the next digit (7) from the dividend after 42, then repeat: 427 / 136

Going ahead to step 7:
When dividing 427 by 136, we get 3 with a remainder of 19.
The next digit of our result is 3. 
Result so far: 59843.0
If we subtract 408 from 427, we get 19.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 136

Step 8:
190 divided by 136 is 1 with a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 598431.0
Subtract 136 from 190 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 9:
When dividing 540 by 136, we get 3 with a remainder of 132.
Write down 3 as next digit of the result. 
Result so far: 598431.3
Subtracting 408 from 540 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 10:
136 goes into 1320 9 times with a remainder of 96.
The next digit of our result is 9. 
Result so far: 598431.39
If we take 1224 away from 1320, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 11:
When dividing 960 by 136, we get 7 with a remainder of 8.
The next digit of our result is 7. 
Result so far: 598431.397
Subtract 952 from 960 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
80 divided by 136 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 598431.397
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 13:
800 divided by 136 is 5 with a remainder of 120.
The number 5 becomes the next digit in our result. 
Result so far: 598431.39705
If we subtract 680 from 800, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 14:
136 can be fit into 1200 8 times, resulting in a remainder of 112.
The number 8 becomes the next digit in our result. 
Result so far: 598431.397058
Subtract 1088 from 1200 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 15:
1120 divided by 136 is 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 598431.3970588
The remainder is 32 after subtracting 1088 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 598431.3970588 with a remaining 3.2e-07.
