We're dividing 87193261 by 515 
Our goal is to divide 87193261 by 515.

Moving on to step 1:
If we divide 8 by 515, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 515

On to step 2:
515 can be fit into 87 0 times, resulting in a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Bring next digit (1) of the dividend behind the 87 and repeat the process: 871 / 515

Advancing to step 3:
When dividing 871 by 515, we get 1 with a remainder of 356.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 515 from 871 leaves us with 356.
Grab the next digit (9) from the dividend, add it to 356, then carry on: 3569 / 515

On to step 4:
The number 515 fits into 3569 6 times, leaving a remainder of 479.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 3090 from 3569, we get 479.
Bring next digit (3) of the dividend behind the 479 and repeat the process: 4793 / 515

Advancing to step 5:
515 goes into 4793 9 times with a remainder of 158.
The number 9 becomes the next digit in our result. 
Result so far: 169.0
Subtracting 4635 from 4793 leaves us with 158.
Fetch the next digit (2) from the dividend, attach it to 158 and continue: 1582 / 515

On to step 6:
The number 515 fits into 1582 3 times, leaving a remainder of 37.
The next digit of our result is 3. 
Result so far: 1693.0
If we take 1545 away from 1582, we end up with 37.
Bring next digit (6) of the dividend behind the 37 and repeat the process: 376 / 515

Step 7:
515 goes into 376 0 times with a remainder of 376.
The number 0 becomes the next digit in our result. 
Result so far: 16930.0
Deduct 0 from 376 and we're left with 376.
Include the next digit (1) from the dividend after 376, then repeat: 3761 / 515

Let's proceed to step 8:
The number 515 fits into 3761 7 times, leaving a remainder of 156.
Record the quotient 7 as the next digit in the result. 
Result so far: 169307.0
Deduct 3605 from 3761 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 9:
The number 515 fits into 1560 3 times, leaving a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 169307.3
If we take 1545 away from 1560, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
515 can be fit into 150 0 times, resulting in a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 169307.3
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 11:
515 can be fit into 1500 2 times, resulting in a remainder of 470.
Put 2 as the next digit of the answer. 
Result so far: 169307.302
Deduct 1030 from 1500 and we're left with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

On to step 12:
515 can be fit into 4700 9 times, resulting in a remainder of 65.
The number 9 becomes the next digit in our result. 
Result so far: 169307.3029
Subtracting 4635 from 4700 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 13:
650 divided by 515 is 1 with a remainder of 135.
Put 1 as the next digit of the answer. 
Result so far: 169307.30291
If we subtract 515 from 650, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 14:
1350 divided by 515 is 2 with a remainder of 320.
Use 2 as the next digit of our solution. 
Result so far: 169307.302912
If we take 1030 away from 1350, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 15:
The number 515 fits into 3200 6 times, leaving a remainder of 110.
Put 6 as the next digit of the answer. 
Result so far: 169307.3029126
Deduct 3090 from 3200 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 16:
515 can be fit into 1100 2 times, resulting in a remainder of 70.
The number 2 becomes the next digit in our result. 
Result so far: 169307.30291262
The remainder is 70 after subtracting 1030 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 169307.30291262 and a remainder of 7e-08.
