658553 ÷ 39 
We're looking to find how many times 39 goes into 658553.

Step 1:
39 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 39

Going ahead to step 2:
The number 39 fits into 65 1 times, leaving a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 39 from 65 and we're left with 26.
Fetch the next digit (8) from the dividend, attach it to 26 and continue: 268 / 39

On to step 3:
39 can be fit into 268 6 times, resulting in a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
The remainder is 34 after subtracting 234 from 268.
Fetch the next digit (5) from the dividend, attach it to 34 and continue: 345 / 39

Step 4:
39 goes into 345 8 times with a remainder of 33.
Write down 8 as next digit of the result. 
Result so far: 168.0
If we take 312 away from 345, we end up with 33.
Include the next digit (5) from the dividend after 33, then repeat: 335 / 39

Step 5:
If we divide 335 by 39, we get 8 and a remainder of 23.
Write down 8 as next digit of the result. 
Result so far: 1688.0
If we take 312 away from 335, we end up with 23.
Bring next digit (3) of the dividend behind the 23 and repeat the process: 233 / 39

Let's proceed to step 6:
39 can be fit into 233 5 times, resulting in a remainder of 38.
Use 5 as the next digit of our solution. 
Result so far: 16885.0
If we take 195 away from 233, we end up 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 7:
39 can be fit into 380 9 times, resulting in a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 16885.9
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.

Moving on to step 8:
290 divided by 39 is 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 16885.97
If we subtract 273 from 290, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
If we divide 170 by 39, we get 4 and a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 16885.974
If we subtract 156 from 170, we get 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 10:
The number 39 fits into 140 3 times, leaving a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 16885.9743
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.

Advancing to step 11:
39 can be fit into 230 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 16885.97435
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.

Moving on to step 12:
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: 16885.974358
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.

Advancing to step 13:
39 goes into 380 9 times with a remainder of 29.
The next digit of our result is 9. 
Result so far: 16885.9743589
Deduct 351 from 380 and we're left 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.

Step 14:
39 goes into 290 7 times with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 16885.97435897
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.

Our division results in 16885.97435897 with a remaining 1.7e-08.
