527170 ÷ 39 
We want to figure out the number of times 527170 can be divided by 39.

On to step 1:
When dividing 5 by 39, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 39

Let's proceed to step 2:
39 goes into 52 1 times with a remainder of 13.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 39 from 52 leaves us with 13.
Include the next digit (7) from the dividend after 13, then repeat: 137 / 39

On to step 3:
The number 39 fits into 137 3 times, leaving a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 117 from 137 and we're left with 20.
Grab the next digit (1) from the dividend, add it to 20, then carry on: 201 / 39

Step 4:
If we divide 201 by 39, we get 5 and a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 135.0
Subtracting 195 from 201 leaves us with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 39

Advancing to step 5:
When dividing 67 by 39, we get 1 with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 1351.0
If we take 39 away from 67, we end up with 28.
Take the next digit (0) from the dividend and append it to 28, then repeat: 280 / 39

On to step 6:
When dividing 280 by 39, we get 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 13517.0
Subtract 273 from 280 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
When dividing 70 by 39, we get 1 with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 13517.1
If we take 39 away from 70, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 8:
If we divide 310 by 39, we get 7 and a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 13517.17
The remainder is 37 after subtracting 273 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 9:
If we divide 370 by 39, we get 9 and a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 13517.179
If we subtract 351 from 370, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 10:
The number 39 fits into 190 4 times, leaving a remainder of 34.
The next digit of our result is 4. 
Result so far: 13517.1794
Subtracting 156 from 190 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 11:
When dividing 340 by 39, we get 8 with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 13517.17948
Deduct 312 from 340 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 12:
The number 39 fits into 280 7 times, leaving a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 13517.179487
If we take 273 away from 280, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 13:
If we divide 70 by 39, we get 1 and a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 13517.1794871
If we take 39 away from 70, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 14:
When dividing 310 by 39, we get 7 with a remainder of 37.
The next digit of our result is 7. 
Result so far: 13517.17948717
If we subtract 273 from 310, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The final outcome is 13517.17948717, with a leftover of 3.7e-08.
