21878411 divided by 203 
The aim is to understand the frequency of 203 in 21878411.

Advancing to step 1:
If we divide 2 by 203, we get 0 and 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.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 203

Step 2:
203 goes into 21 0 times with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 203

Let's proceed to step 3:
218 divided by 203 is 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 203 from 218, we get 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 203

Moving on to step 4:
The number 203 fits into 157 0 times, leaving a remainder of 157.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 157 to get 157.
Bring next digit (8) of the dividend behind the 157 and repeat the process: 1578 / 203

Step 5:
203 goes into 1578 7 times with a remainder of 157.
Put 7 as the next digit of the answer. 
Result so far: 107.0
Subtracting 1421 from 1578 leaves us with 157.
Fetch the next digit (4) from the dividend, attach it to 157 and continue: 1574 / 203

Advancing to step 6:
When dividing 1574 by 203, we get 7 with a remainder of 153.
Use 7 as the next digit of our solution. 
Result so far: 1077.0
Subtracting 1421 from 1574 leaves us with 153.
Grab the next digit (1) from the dividend, add it to 153, then carry on: 1531 / 203

Advancing to step 7:
When dividing 1531 by 203, we get 7 with a remainder of 110.
Record the quotient 7 as the next digit in the result. 
Result so far: 10777.0
If we take 1421 away from 1531, we end up with 110.
Append the next digit (1) from the dividend to 110 and continue with: 1101 / 203

Let's proceed to step 8:
If we divide 1101 by 203, we get 5 and a remainder of 86.
Put 5 as the next digit of the answer. 
Result so far: 107775.0
If we subtract 1015 from 1101, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 9:
When dividing 860 by 203, we get 4 with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 107775.4
The remainder is 48 after subtracting 812 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
480 divided by 203 is 2 with a remainder of 74.
The next digit of our result is 2. 
Result so far: 107775.42
Subtracting 406 from 480 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 11:
When dividing 740 by 203, we get 3 with a remainder of 131.
Put 3 as the next digit of the answer. 
Result so far: 107775.423
Subtracting 609 from 740 leaves us 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.

Moving on to step 12:
If we divide 1310 by 203, we get 6 and a remainder of 92.
Use 6 as the next digit of our solution. 
Result so far: 107775.4236
If we subtract 1218 from 1310, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 13:
The number 203 fits into 920 4 times, leaving a remainder of 108.
Use 4 as the next digit of our solution. 
Result so far: 107775.42364
If we take 812 away from 920, we end up 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.

Let's proceed to step 14:
When dividing 1080 by 203, we get 5 with a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 107775.423645
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.

Step 15:
When dividing 650 by 203, we get 3 with a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 107775.4236453
If we take 609 away from 650, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 16:
The number 203 fits into 410 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 107775.42364532
If we subtract 406 from 410, we 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.

The final outcome is 107775.42364532, with a leftover of 4e-09.
