We look at the division of 13696399 by 87 
Our goal is to divide 13696399 by 87.

Moving on to step 1:
87 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 87

Advancing to step 2:
87 goes into 13 0 times with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 87

Let's proceed to step 3:
If we divide 136 by 87, we get 1 and a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 87 from 136 to get 49.
Fetch the next digit (9) from the dividend, attach it to 49 and continue: 499 / 87

Let's proceed to step 4:
87 can be fit into 499 5 times, resulting in a remainder of 64.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 435 away from 499, we end up with 64.
Fetch the next digit (6) from the dividend, attach it to 64 and continue: 646 / 87

Advancing to step 5:
If we divide 646 by 87, we get 7 and a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 157.0
The remainder is 37 after subtracting 609 from 646.
Include the next digit (3) from the dividend after 37, then repeat: 373 / 87

Advancing to step 6:
When dividing 373 by 87, we get 4 with a remainder of 25.
Record the quotient 4 as the next digit in the result. 
Result so far: 1574.0
The remainder is 25 after subtracting 348 from 373.
Fetch the next digit (9) from the dividend, attach it to 25 and continue: 259 / 87

Step 7:
If we divide 259 by 87, we get 2 and a remainder of 85.
Write down 2 as next digit of the result. 
Result so far: 15742.0
The remainder is 85 after subtracting 174 from 259.
Include the next digit (9) from the dividend after 85, then repeat: 859 / 87

Going ahead to step 8:
If we divide 859 by 87, we get 9 and a remainder of 76.
Record the quotient 9 as the next digit in the result. 
Result so far: 157429.0
The remainder is 76 after subtracting 783 from 859.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 9:
When dividing 760 by 87, we get 8 with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 157429.8
If we subtract 696 from 760, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 10:
640 divided by 87 is 7 with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 157429.87
Deduct 609 from 640 and we're left 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.

Let's proceed to step 11:
87 can be fit into 310 3 times, resulting in a remainder of 49.
The number 3 becomes the next digit in our result. 
Result so far: 157429.873
If we subtract 261 from 310, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 12:
When dividing 490 by 87, we get 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 157429.8735
If we subtract 435 from 490, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 13:
87 can be fit into 550 6 times, resulting in a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 157429.87356
Deduct 522 from 550 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.

Going ahead to step 14:
87 can be fit into 280 3 times, resulting in a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 157429.873563
Subtract 261 from 280 to 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.

On to step 15:
When dividing 190 by 87, we get 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 157429.8735632
Subtract 174 from 190 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 16:
The number 87 fits into 160 1 times, leaving a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 157429.87356321
Subtract 87 from 160 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

The quotient of the division is 157429.87356321, and the remainder is 7.3e-08.
