Let's divide 15715570 by 591
We're looking to find how many times 591 goes into 15715570.

Step 1:
When dividing 1 by 591, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 591

On to step 2:
If we divide 15 by 591, we get 0 and a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 591

Advancing to step 3:
If we divide 157 by 591, we get 0 and a remainder of 157.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 157, we get 157.
Bring next digit (1) of the dividend behind the 157 and repeat the process: 1571 / 591

On to step 4:
1571 divided by 591 is 2 with a remainder of 389.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 1182 from 1571 and we're left with 389.
Fetch the next digit (5) from the dividend, attach it to 389 and continue: 3895 / 591

Step 5:
591 goes into 3895 6 times with a remainder of 349.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
If we subtract 3546 from 3895, we get 349.
Fetch the next digit (5) from the dividend, attach it to 349 and continue: 3495 / 591

Step 6:
If we divide 3495 by 591, we get 5 and a remainder of 540.
Record the quotient 5 as the next digit in the result. 
Result so far: 265.0
Subtracting 2955 from 3495 leaves us with 540.
Fetch the next digit (7) from the dividend, attach it to 540 and continue: 5407 / 591

Step 7:
5407 divided by 591 is 9 with a remainder of 88.
Use 9 as the next digit of our solution. 
Result so far: 2659.0
If we subtract 5319 from 5407, we get 88.
Fetch the next digit (0) from the dividend, attach it to 88 and continue: 880 / 591

Going ahead to step 8:
If we divide 880 by 591, we get 1 and a remainder of 289.
The number 1 becomes the next digit in our result. 
Result so far: 26591.0
If we subtract 591 from 880, we get 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Going ahead to step 9:
The number 591 fits into 2890 4 times, leaving a remainder of 526.
Put 4 as the next digit of the answer. 
Result so far: 26591.4
If we subtract 2364 from 2890, we get 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Step 10:
591 can be fit into 5260 8 times, resulting in a remainder of 532.
Record the quotient 8 as the next digit in the result. 
Result so far: 26591.48
Deduct 4728 from 5260 and we're left with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Going ahead to step 11:
5320 divided by 591 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 26591.489
If we take 5319 away from 5320, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 12:
10 divided by 591 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 26591.489
Subtracting 0 from 10 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.

On to step 13:
100 divided by 591 is 0 with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 26591.489
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The quotient of the division is 26591.489, and the remainder is 0.0001.
