Let's divide 81974978 by 206
The aim is to understand the frequency of 206 in 81974978.

Advancing to step 1:
If we divide 8 by 206, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 206

Moving on to step 2:
206 can be fit into 81 0 times, resulting in a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Grab the next digit (9) from the dividend, add it to 81, then carry on: 819 / 206

Let's proceed to step 3:
When dividing 819 by 206, we get 3 with a remainder of 201.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 201 after subtracting 618 from 819.
Include the next digit (7) from the dividend after 201, then repeat: 2017 / 206

Let's proceed to step 4:
When dividing 2017 by 206, we get 9 with a remainder of 163.
Write down 9 as next digit of the result. 
Result so far: 39.0
Deduct 1854 from 2017 and we're left with 163.
Append the next digit (4) from the dividend to 163 and continue with: 1634 / 206

Going ahead to step 5:
The number 206 fits into 1634 7 times, leaving a remainder of 192.
Use 7 as the next digit of our solution. 
Result so far: 397.0
The remainder is 192 after subtracting 1442 from 1634.
Bring next digit (9) of the dividend behind the 192 and repeat the process: 1929 / 206

On to step 6:
1929 divided by 206 is 9 with a remainder of 75.
Put 9 as the next digit of the answer. 
Result so far: 3979.0
Deduct 1854 from 1929 and we're left with 75.
Append the next digit (7) from the dividend to 75 and continue with: 757 / 206

Step 7:
757 divided by 206 is 3 with a remainder of 139.
Record the quotient 3 as the next digit in the result. 
Result so far: 39793.0
If we subtract 618 from 757, we get 139.
Bring next digit (8) of the dividend behind the 139 and repeat the process: 1398 / 206

Advancing to step 8:
206 can be fit into 1398 6 times, resulting in a remainder of 162.
Write down 6 as next digit of the result. 
Result so far: 397936.0
The remainder is 162 after subtracting 1236 from 1398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Advancing to step 9:
206 can be fit into 1620 7 times, resulting in a remainder of 178.
The next digit of our result is 7. 
Result so far: 397936.7
Subtract 1442 from 1620 to get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Moving on to step 10:
1780 divided by 206 is 8 with a remainder of 132.
Write down 8 as next digit of the result. 
Result so far: 397936.78
Subtract 1648 from 1780 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 11:
When dividing 1320 by 206, we get 6 with a remainder of 84.
Record the quotient 6 as the next digit in the result. 
Result so far: 397936.786
The remainder is 84 after subtracting 1236 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 12:
When dividing 840 by 206, we get 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 397936.7864
The remainder is 16 after subtracting 824 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
If we divide 160 by 206, we get 0 and a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 397936.7864
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 14:
When dividing 1600 by 206, we get 7 with a remainder of 158.
Put 7 as the next digit of the answer. 
Result so far: 397936.786407
Subtracting 1442 from 1600 leaves us with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 15:
When dividing 1580 by 206, we get 7 with a remainder of 138.
Record the quotient 7 as the next digit in the result. 
Result so far: 397936.7864077
Deduct 1442 from 1580 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

The final result is 397936.7864077 with a remainder of 1.38e-06.
