39613386 ÷ 102 
Our goal is to divide 39613386 by 102.

On to step 1:
If we divide 3 by 102, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 102

Step 2:
102 can be fit into 39 0 times, resulting in a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Include the next digit (6) from the dividend after 39, then repeat: 396 / 102

Let's proceed to step 3:
If we divide 396 by 102, we get 3 and a remainder of 90.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 306 from 396 and we're left with 90.
Append the next digit (1) from the dividend to 90 and continue with: 901 / 102

Going ahead to step 4:
102 goes into 901 8 times with a remainder of 85.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Subtract 816 from 901 to get 85.
Include the next digit (3) from the dividend after 85, then repeat: 853 / 102

Let's proceed to step 5:
When dividing 853 by 102, we get 8 with a remainder of 37.
Use 8 as the next digit of our solution. 
Result so far: 388.0
Subtracting 816 from 853 leaves us with 37.
Take the next digit (3) from the dividend and append it to 37, then repeat: 373 / 102

Step 6:
102 goes into 373 3 times with a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 3883.0
If we subtract 306 from 373, we get 67.
Append the next digit (8) from the dividend to 67 and continue with: 678 / 102

Advancing to step 7:
The number 102 fits into 678 6 times, leaving a remainder of 66.
The number 6 becomes the next digit in our result. 
Result so far: 38836.0
If we take 612 away from 678, we end up with 66.
Grab the next digit (6) from the dividend, add it to 66, then carry on: 666 / 102

On to step 8:
102 goes into 666 6 times with a remainder of 54.
Put 6 as the next digit of the answer. 
Result so far: 388366.0
If we subtract 612 from 666, we 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.

On to step 9:
If we divide 540 by 102, we get 5 and a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 388366.5
If we subtract 510 from 540, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
The number 102 fits into 300 2 times, leaving a remainder of 96.
Write down 2 as next digit of the result. 
Result so far: 388366.52
Subtract 204 from 300 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 11:
When dividing 960 by 102, we get 9 with a remainder of 42.
Use 9 as the next digit of our solution. 
Result so far: 388366.529
If we take 918 away from 960, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 12:
102 goes into 420 4 times with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 388366.5294
Subtracting 408 from 420 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 13:
102 can be fit into 120 1 times, resulting in a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 388366.52941
Subtracting 102 from 120 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 14:
102 goes into 180 1 times with a remainder of 78.
Put 1 as the next digit of the answer. 
Result so far: 388366.529411
The remainder is 78 after subtracting 102 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Our division results in 388366.529411 with a remaining 7.8e-06.
