We divide 42423891 by 205
The aim is to understand the frequency of 205 in 42423891.

Step 1:
When dividing 4 by 205, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 205

Let's proceed to step 2:
205 goes into 42 0 times with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Take the next digit (4) from the dividend and append it to 42, then repeat: 424 / 205

Advancing to step 3:
424 divided by 205 is 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 410 from 424 and we're left with 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 205

On to step 4:
The number 205 fits into 142 0 times, leaving a remainder of 142.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtracting 0 from 142 leaves us with 142.
Take the next digit (3) from the dividend and append it to 142, then repeat: 1423 / 205

Going ahead to step 5:
When dividing 1423 by 205, we get 6 with a remainder of 193.
Put 6 as the next digit of the answer. 
Result so far: 206.0
If we subtract 1230 from 1423, we get 193.
Include the next digit (8) from the dividend after 193, then repeat: 1938 / 205

Let's proceed to step 6:
If we divide 1938 by 205, we get 9 and a remainder of 93.
Write down 9 as next digit of the result. 
Result so far: 2069.0
Deduct 1845 from 1938 and we're left with 93.
Grab the next digit (9) from the dividend, add it to 93, then carry on: 939 / 205

Moving on to step 7:
When dividing 939 by 205, we get 4 with a remainder of 119.
The next digit of our result is 4. 
Result so far: 20694.0
Subtracting 820 from 939 leaves us with 119.
Fetch the next digit (1) from the dividend, attach it to 119 and continue: 1191 / 205

On to step 8:
1191 divided by 205 is 5 with a remainder of 166.
Record the quotient 5 as the next digit in the result. 
Result so far: 206945.0
Subtracting 1025 from 1191 leaves us with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Step 9:
1660 divided by 205 is 8 with a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 206945.8
If we take 1640 away from 1660, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
The number 205 fits into 200 0 times, leaving a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 206945.8
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 11:
When dividing 2000 by 205, we get 9 with a remainder of 155.
Use 9 as the next digit of our solution. 
Result so far: 206945.809
If we subtract 1845 from 2000, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Advancing to step 12:
205 can be fit into 1550 7 times, resulting in a remainder of 115.
The number 7 becomes the next digit in our result. 
Result so far: 206945.8097
Subtract 1435 from 1550 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Let's proceed to step 13:
If we divide 1150 by 205, we get 5 and a remainder of 125.
The next digit of our result is 5. 
Result so far: 206945.80975
If we subtract 1025 from 1150, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 14:
205 can be fit into 1250 6 times, resulting in a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 206945.809756
Subtracting 1230 from 1250 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 15:
205 can be fit into 200 0 times, resulting in a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 206945.809756
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 16:
When dividing 2000 by 205, we get 9 with a remainder of 155.
Use 9 as the next digit of our solution. 
Result so far: 206945.80975609
If we take 1845 away from 2000, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

The final outcome is 206945.80975609, with a leftover of 1.55e-07.
