81678386 ÷ 39 
We want to divide 81678386 by 39.

Advancing to step 1:
39 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 39

Step 2:
If we divide 81 by 39, we get 2 and a remainder of 3.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 78 from 81 to get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 39

Let's proceed to step 3:
If we divide 36 by 39, we get 0 and a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Deduct 0 from 36 and we're left with 36.
Take the next digit (7) from the dividend and append it to 36, then repeat: 367 / 39

Let's proceed to step 4:
When dividing 367 by 39, we get 9 with a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 209.0
Deduct 351 from 367 and we're left with 16.
Grab the next digit (8) from the dividend, add it to 16, then carry on: 168 / 39

On to step 5:
168 divided by 39 is 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 2094.0
The remainder is 12 after subtracting 156 from 168.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 39

Moving on to step 6:
39 can be fit into 123 3 times, resulting in a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 20943.0
Deduct 117 from 123 and we're left with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 39

Step 7:
When dividing 68 by 39, we get 1 with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 209431.0
Subtract 39 from 68 to get 29.
Append the next digit (6) from the dividend to 29 and continue with: 296 / 39

Let's proceed to step 8:
If we divide 296 by 39, we get 7 and a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 2094317.0
If we take 273 away from 296, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 9:
39 can be fit into 230 5 times, resulting in a remainder of 35.
The next digit of our result is 5. 
Result so far: 2094317.5
If we take 195 away from 230, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 10:
If we divide 350 by 39, we get 8 and a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 2094317.58
Subtracting 312 from 350 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 11:
When dividing 380 by 39, we get 9 with a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 2094317.589
Subtracting 351 from 380 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 12:
290 divided by 39 is 7 with a remainder of 17.
The next digit of our result is 7. 
Result so far: 2094317.5897
Deduct 273 from 290 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 13:
The number 39 fits into 170 4 times, leaving a remainder of 14.
The next digit of our result is 4. 
Result so far: 2094317.58974
If we take 156 away from 170, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 14:
If we divide 140 by 39, we get 3 and a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 2094317.589743
Subtracting 117 from 140 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 15:
When dividing 230 by 39, we get 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 2094317.5897435
Subtract 195 from 230 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 16:
350 divided by 39 is 8 with a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 2094317.58974358
Subtracting 312 from 350 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Our division results in 2094317.58974358 with a remaining 3.8e-08.
