39912623 ÷ 986 
Let's see how many times 986 fits into 39912623.

Moving on to step 1:
When dividing 3 by 986, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 986

On to step 2:
986 can be fit into 39 0 times, resulting in a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Fetch the next digit (9) from the dividend, attach it to 39 and continue: 399 / 986

Moving on to step 3:
986 can be fit into 399 0 times, resulting in a remainder of 399.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 399 after subtracting 0 from 399.
Take the next digit (1) from the dividend and append it to 399, then repeat: 3991 / 986

Advancing to step 4:
The number 986 fits into 3991 4 times, leaving a remainder of 47.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 3944 from 3991 leaves us with 47.
Fetch the next digit (2) from the dividend, attach it to 47 and continue: 472 / 986

Step 5:
If we divide 472 by 986, we get 0 and a remainder of 472.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Subtract 0 from 472 to get 472.
Fetch the next digit (6) from the dividend, attach it to 472 and continue: 4726 / 986

Going ahead to step 6:
The number 986 fits into 4726 4 times, leaving a remainder of 782.
Write down 4 as next digit of the result. 
Result so far: 404.0
If we take 3944 away from 4726, we end up with 782.
Fetch the next digit (2) from the dividend, attach it to 782 and continue: 7822 / 986

On to step 7:
7822 divided by 986 is 7 with a remainder of 920.
The next digit of our result is 7. 
Result so far: 4047.0
Deduct 6902 from 7822 and we're left with 920.
Include the next digit (3) from the dividend after 920, then repeat: 9203 / 986

Moving on to step 8:
The number 986 fits into 9203 9 times, leaving a remainder of 329.
The number 9 becomes the next digit in our result. 
Result so far: 40479.0
If we take 8874 away from 9203, we end up with 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Let's proceed to step 9:
When dividing 3290 by 986, we get 3 with a remainder of 332.
The next digit of our result is 3. 
Result so far: 40479.3
The remainder is 332 after subtracting 2958 from 3290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Advancing to step 10:
When dividing 3320 by 986, we get 3 with a remainder of 362.
The number 3 becomes the next digit in our result. 
Result so far: 40479.33
Deduct 2958 from 3320 and we're left with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Our division results in 40479.33 with a remaining 0.362.
