Let's divide 668601 by 39
Let's see how many times 39 fits into 668601.

Moving on to step 1:
If we divide 6 by 39, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 39

Let's proceed to step 2:
If we divide 66 by 39, we get 1 and a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 39 from 66 to get 27.
Bring next digit (8) of the dividend behind the 27 and repeat the process: 278 / 39

Step 3:
The number 39 fits into 278 7 times, leaving a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtracting 273 from 278 leaves us with 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 39

Advancing to step 4:
If we divide 56 by 39, we get 1 and a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 171.0
Subtracting 39 from 56 leaves us with 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 39

Step 5:
If we divide 170 by 39, we get 4 and a remainder of 14.
The next digit of our result is 4. 
Result so far: 1714.0
Subtract 156 from 170 to get 14.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 39

Step 6:
39 goes into 141 3 times with a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 17143.0
If we subtract 117 from 141, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 7:
The number 39 fits into 240 6 times, leaving a remainder of 6.
The next digit of our result is 6. 
Result so far: 17143.6
The remainder is 6 after subtracting 234 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
60 divided by 39 is 1 with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 17143.61
Deduct 39 from 60 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 9:
39 goes into 210 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 17143.615
If we subtract 195 from 210, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 10:
If we divide 150 by 39, we get 3 and a remainder of 33.
The next digit of our result is 3. 
Result so far: 17143.6153
If we take 117 away from 150, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 11:
330 divided by 39 is 8 with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 17143.61538
Subtracting 312 from 330 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.

Advancing to step 12:
180 divided by 39 is 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 17143.615384
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 13:
When dividing 240 by 39, we get 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 17143.6153846
Subtracting 234 from 240 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 14:
When dividing 60 by 39, we get 1 with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 17143.61538461
Subtracting 39 from 60 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Our division results in 17143.61538461 with a remaining 2.1e-08.
