758663 ÷ 39 
We're looking to find how many times 39 goes into 758663.

Let's proceed to step 1:
When dividing 7 by 39, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 39

Step 2:
The number 39 fits into 75 1 times, leaving a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 36 after subtracting 39 from 75.
Take the next digit (8) from the dividend and append it to 36, then repeat: 368 / 39

Let's proceed to step 3:
When dividing 368 by 39, we get 9 with a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we subtract 351 from 368, we get 17.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 39

Let's proceed to step 4:
When dividing 176 by 39, we get 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 194.0
If we subtract 156 from 176, we get 20.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 39

Moving on to step 5:
When dividing 206 by 39, we get 5 with a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 1945.0
Deduct 195 from 206 and we're left with 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 39

Advancing to step 6:
The number 39 fits into 113 2 times, leaving a remainder of 35.
The next digit of our result is 2. 
Result so far: 19452.0
Deduct 78 from 113 and we're left 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.

Step 7:
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: 19452.8
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.

On to step 8:
39 can be fit into 380 9 times, resulting in a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 19452.89
The remainder is 29 after subtracting 351 from 380.
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 9:
When dividing 290 by 39, we get 7 with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 19452.897
The remainder is 17 after subtracting 273 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 10:
The number 39 fits into 170 4 times, leaving a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 19452.8974
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.

Advancing to step 11:
If we divide 140 by 39, we get 3 and a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 19452.89743
If we take 117 away from 140, 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.

Moving on to step 12:
When dividing 230 by 39, we get 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 19452.897435
Deduct 195 from 230 and we're left 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.

Step 13:
If we divide 350 by 39, we get 8 and a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 19452.8974358
Deduct 312 from 350 and we're left 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.

Going ahead to step 14:
39 can be fit into 380 9 times, resulting in a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 19452.89743589
If we subtract 351 from 380, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final outcome is 19452.89743589, with a leftover of 2.9e-08.
