Let's divide 903397 by 87
Our goal is to divide 903397 by 87.

Advancing to step 1:
If we divide 9 by 87, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 87

On to step 2:
90 divided by 87 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 87 from 90 leaves us with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 87

Going ahead to step 3:
If we divide 33 by 87, we get 0 and a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 33 after subtracting 0 from 33.
Fetch the next digit (3) from the dividend, attach it to 33 and continue: 333 / 87

Going ahead to step 4:
If we divide 333 by 87, we get 3 and a remainder of 72.
Put 3 as the next digit of the answer. 
Result so far: 103.0
Subtracting 261 from 333 leaves us with 72.
Bring next digit (9) of the dividend behind the 72 and repeat the process: 729 / 87

Going ahead to step 5:
If we divide 729 by 87, we get 8 and a remainder of 33.
Write down 8 as next digit of the result. 
Result so far: 1038.0
If we take 696 away from 729, we end up with 33.
Bring next digit (7) of the dividend behind the 33 and repeat the process: 337 / 87

Moving on to step 6:
87 can be fit into 337 3 times, resulting in a remainder of 76.
The next digit of our result is 3. 
Result so far: 10383.0
Deduct 261 from 337 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 7:
When dividing 760 by 87, we get 8 with a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 10383.8
If we take 696 away from 760, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 8:
87 can be fit into 640 7 times, resulting in a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 10383.87
Subtracting 609 from 640 leaves us 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.

On to step 9:
If we divide 310 by 87, we get 3 and a remainder of 49.
Write down 3 as next digit of the result. 
Result so far: 10383.873
If we take 261 away from 310, we end up with 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 10:
87 can be fit into 490 5 times, resulting in a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 10383.8735
If we take 435 away from 490, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 11:
When dividing 550 by 87, we get 6 with a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 10383.87356
The remainder is 28 after subtracting 522 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 12:
If we divide 280 by 87, we get 3 and a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 10383.873563
If we subtract 261 from 280, 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.

On to step 13:
87 can be fit into 190 2 times, resulting in a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 10383.8735632
If we subtract 174 from 190, we 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.

Let's proceed to step 14:
When dividing 160 by 87, we get 1 with a remainder of 73.
Put 1 as the next digit of the answer. 
Result so far: 10383.87356321
The remainder is 73 after subtracting 87 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

The final result is 10383.87356321 with a remainder of 7.3e-08.
