Let's divide 28161306 by 203
We want to divide 28161306 by 203.

Going ahead to step 1:
203 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 203

Let's proceed to step 2:
203 can be fit into 28 0 times, resulting in a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Bring next digit (1) of the dividend behind the 28 and repeat the process: 281 / 203

Going ahead to step 3:
The number 203 fits into 281 1 times, leaving a remainder of 78.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 203 away from 281, we end up with 78.
Take the next digit (6) from the dividend and append it to 78, then repeat: 786 / 203

Moving on to step 4:
203 goes into 786 3 times with a remainder of 177.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 177 after subtracting 609 from 786.
Include the next digit (1) from the dividend after 177, then repeat: 1771 / 203

Advancing to step 5:
The number 203 fits into 1771 8 times, leaving a remainder of 147.
Use 8 as the next digit of our solution. 
Result so far: 138.0
If we take 1624 away from 1771, we end up with 147.
Take the next digit (3) from the dividend and append it to 147, then repeat: 1473 / 203

Step 6:
1473 divided by 203 is 7 with a remainder of 52.
The next digit of our result is 7. 
Result so far: 1387.0
If we subtract 1421 from 1473, we get 52.
Append the next digit (0) from the dividend to 52 and continue with: 520 / 203

On to step 7:
When dividing 520 by 203, we get 2 with a remainder of 114.
The number 2 becomes the next digit in our result. 
Result so far: 13872.0
Subtract 406 from 520 to get 114.
Append the next digit (6) from the dividend to 114 and continue with: 1146 / 203

Going ahead to step 8:
203 can be fit into 1146 5 times, resulting in a remainder of 131.
The number 5 becomes the next digit in our result. 
Result so far: 138725.0
Deduct 1015 from 1146 and we're left with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Step 9:
1310 divided by 203 is 6 with a remainder of 92.
Put 6 as the next digit of the answer. 
Result so far: 138725.6
The remainder is 92 after subtracting 1218 from 1310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 10:
920 divided by 203 is 4 with a remainder of 108.
Write down 4 as next digit of the result. 
Result so far: 138725.64
Deduct 812 from 920 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 11:
When dividing 1080 by 203, we get 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 138725.645
The remainder is 65 after subtracting 1015 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 12:
When dividing 650 by 203, we get 3 with a remainder of 41.
Record the quotient 3 as the next digit in the result. 
Result so far: 138725.6453
The remainder is 41 after subtracting 609 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 13:
203 goes into 410 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 138725.64532
Subtract 406 from 410 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
203 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 138725.64532
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 15:
When dividing 400 by 203, we get 1 with a remainder of 197.
Record the quotient 1 as the next digit in the result. 
Result so far: 138725.6453201
The remainder is 197 after subtracting 203 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Advancing to step 16:
The number 203 fits into 1970 9 times, leaving a remainder of 143.
Use 9 as the next digit of our solution. 
Result so far: 138725.64532019
Subtract 1827 from 1970 to get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

After the division, we end up with 138725.64532019 and a remainder of 1.43e-07.
