591991 ÷ 39 
Our goal is to divide 591991 by 39.

On to step 1:
When dividing 5 by 39, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 39

Advancing to step 2:
If we divide 59 by 39, we get 1 and a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 39 away from 59, we end up with 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 39

Advancing to step 3:
201 divided by 39 is 5 with a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 195 from 201 to get 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 39

Advancing to step 4:
39 goes into 69 1 times with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 151.0
If we subtract 39 from 69, we get 30.
Append the next digit (9) from the dividend to 30 and continue with: 309 / 39

Going ahead to step 5:
39 can be fit into 309 7 times, resulting in a remainder of 36.
The number 7 becomes the next digit in our result. 
Result so far: 1517.0
If we take 273 away from 309, we end up with 36.
Include the next digit (1) from the dividend after 36, then repeat: 361 / 39

Going ahead to step 6:
39 can be fit into 361 9 times, resulting in a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 15179.0
Subtracting 351 from 361 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
39 can be fit into 100 2 times, resulting in a remainder of 22.
The next digit of our result is 2. 
Result so far: 15179.2
Deduct 78 from 100 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
If we divide 220 by 39, we get 5 and a remainder of 25.
The next digit of our result is 5. 
Result so far: 15179.25
Deduct 195 from 220 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
250 divided by 39 is 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 15179.256
Subtracting 234 from 250 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
When dividing 160 by 39, we get 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 15179.2564
Deduct 156 from 160 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
39 goes into 40 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 15179.25641
Subtract 39 from 40 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 12:
10 divided by 39 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 15179.25641
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
39 goes into 100 2 times with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 15179.2564102
If we take 78 away from 100, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 14:
The number 39 fits into 220 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 15179.25641025
If we subtract 195 from 220, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 15179.25641025, and the remainder is 2.5e-08.
