We look at the division of 87357291 by 203 
Our goal is to divide 87357291 by 203.

Let's proceed to step 1:
203 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 203

Advancing to step 2:
If we divide 87 by 203, we get 0 and a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Take the next digit (3) from the dividend and append it to 87, then repeat: 873 / 203

Moving on to step 3:
203 goes into 873 4 times with a remainder of 61.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 61 after subtracting 812 from 873.
Grab the next digit (5) from the dividend, add it to 61, then carry on: 615 / 203

On to step 4:
If we divide 615 by 203, we get 3 and a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Deduct 609 from 615 and we're left with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 203

Step 5:
203 can be fit into 67 0 times, resulting in a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 430.0
Deduct 0 from 67 and we're left with 67.
Bring next digit (2) of the dividend behind the 67 and repeat the process: 672 / 203

Step 6:
203 can be fit into 672 3 times, resulting in a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 4303.0
If we take 609 away from 672, we end up with 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 203

Advancing to step 7:
639 divided by 203 is 3 with a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 43033.0
Subtracting 609 from 639 leaves us with 30.
Include the next digit (1) from the dividend after 30, then repeat: 301 / 203

Let's proceed to step 8:
203 can be fit into 301 1 times, resulting in a remainder of 98.
The next digit of our result is 1. 
Result so far: 430331.0
If we subtract 203 from 301, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 9:
The number 203 fits into 980 4 times, leaving a remainder of 168.
Put 4 as the next digit of the answer. 
Result so far: 430331.4
Subtract 812 from 980 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 10:
203 goes into 1680 8 times with a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 430331.48
Subtract 1624 from 1680 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 11:
203 goes into 560 2 times with a remainder of 154.
The number 2 becomes the next digit in our result. 
Result so far: 430331.482
If we take 406 away from 560, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Let's proceed to step 12:
When dividing 1540 by 203, we get 7 with a remainder of 119.
The number 7 becomes the next digit in our result. 
Result so far: 430331.4827
If we take 1421 away from 1540, we end up with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Step 13:
203 can be fit into 1190 5 times, resulting in a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 430331.48275
If we take 1015 away from 1190, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

On to step 14:
203 goes into 1750 8 times with a remainder of 126.
Write down 8 as next digit of the result. 
Result so far: 430331.482758
Deduct 1624 from 1750 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 15:
203 can be fit into 1260 6 times, resulting in a remainder of 42.
The next digit of our result is 6. 
Result so far: 430331.4827586
Deduct 1218 from 1260 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 16:
203 can be fit into 420 2 times, resulting in a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 430331.48275862
If we take 406 away from 420, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 430331.48275862 and a remainder of 1.4e-08.
