We divide 51565910 by 206
The aim is to understand the frequency of 206 in 51565910.

Moving on to step 1:
The number 206 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 206

Going ahead to step 2:
The number 206 fits into 51 0 times, leaving a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Bring next digit (5) of the dividend behind the 51 and repeat the process: 515 / 206

On to step 3:
If we divide 515 by 206, we get 2 and a remainder of 103.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 412 from 515 to get 103.
Append the next digit (6) from the dividend to 103 and continue with: 1036 / 206

Moving on to step 4:
206 can be fit into 1036 5 times, resulting in a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we take 1030 away from 1036, we end up with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 206

Advancing to step 5:
If we divide 65 by 206, we get 0 and a remainder of 65.
The next digit of our result is 0. 
Result so far: 250.0
Deduct 0 from 65 and we're left with 65.
Include the next digit (9) from the dividend after 65, then repeat: 659 / 206

Advancing to step 6:
If we divide 659 by 206, we get 3 and a remainder of 41.
Put 3 as the next digit of the answer. 
Result so far: 2503.0
If we take 618 away from 659, we end up with 41.
Take the next digit (1) from the dividend and append it to 41, then repeat: 411 / 206

Going ahead to step 7:
411 divided by 206 is 1 with a remainder of 205.
The next digit of our result is 1. 
Result so far: 25031.0
The remainder is 205 after subtracting 206 from 411.
Append the next digit (0) from the dividend to 205 and continue with: 2050 / 206

Advancing to step 8:
2050 divided by 206 is 9 with a remainder of 196.
Record the quotient 9 as the next digit in the result. 
Result so far: 250319.0
The remainder is 196 after subtracting 1854 from 2050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Let's proceed to step 9:
206 goes into 1960 9 times with a remainder of 106.
Put 9 as the next digit of the answer. 
Result so far: 250319.9
If we take 1854 away from 1960, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 10:
The number 206 fits into 1060 5 times, leaving a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 250319.95
Subtract 1030 from 1060 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
206 can be fit into 300 1 times, resulting in a remainder of 94.
Use 1 as the next digit of our solution. 
Result so far: 250319.951
Subtract 206 from 300 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 12:
The number 206 fits into 940 4 times, leaving a remainder of 116.
Write down 4 as next digit of the result. 
Result so far: 250319.9514
If we subtract 824 from 940, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 13:
1160 divided by 206 is 5 with a remainder of 130.
Write down 5 as next digit of the result. 
Result so far: 250319.95145
Subtract 1030 from 1160 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 14:
The number 206 fits into 1300 6 times, leaving a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 250319.951456
If we subtract 1236 from 1300, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 15:
When dividing 640 by 206, we get 3 with a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 250319.9514563
Subtracting 618 from 640 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 16:
220 divided by 206 is 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 250319.95145631
Subtract 206 from 220 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 250319.95145631 with a balance of 1.4e-08.
