We divide 81883689 by 207
The aim is to understand the frequency of 207 in 81883689.

Going ahead to step 1:
8 divided by 207 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 207

Step 2:
81 divided by 207 is 0 with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Grab the next digit (8) from the dividend, add it to 81, then carry on: 818 / 207

Let's proceed to step 3:
When dividing 818 by 207, we get 3 with a remainder of 197.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 621 from 818 leaves us with 197.
Take the next digit (8) from the dividend and append it to 197, then repeat: 1978 / 207

Advancing to step 4:
207 can be fit into 1978 9 times, resulting in a remainder of 115.
Write down 9 as next digit of the result. 
Result so far: 39.0
Subtract 1863 from 1978 to get 115.
Append the next digit (3) from the dividend to 115 and continue with: 1153 / 207

Advancing to step 5:
If we divide 1153 by 207, we get 5 and a remainder of 118.
The next digit of our result is 5. 
Result so far: 395.0
Deduct 1035 from 1153 and we're left with 118.
Take the next digit (6) from the dividend and append it to 118, then repeat: 1186 / 207

Moving on to step 6:
1186 divided by 207 is 5 with a remainder of 151.
The number 5 becomes the next digit in our result. 
Result so far: 3955.0
Subtract 1035 from 1186 to get 151.
Take the next digit (8) from the dividend and append it to 151, then repeat: 1518 / 207

On to step 7:
207 can be fit into 1518 7 times, resulting in a remainder of 69.
Record the quotient 7 as the next digit in the result. 
Result so far: 39557.0
Subtracting 1449 from 1518 leaves us with 69.
Take the next digit (9) from the dividend and append it to 69, then repeat: 699 / 207

Going ahead to step 8:
207 can be fit into 699 3 times, resulting in a remainder of 78.
The next digit of our result is 3. 
Result so far: 395573.0
Deduct 621 from 699 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 9:
If we divide 780 by 207, we get 3 and a remainder of 159.
The next digit of our result is 3. 
Result so far: 395573.3
Deduct 621 from 780 and we're left with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Let's proceed to step 10:
207 can be fit into 1590 7 times, resulting in a remainder of 141.
Record the quotient 7 as the next digit in the result. 
Result so far: 395573.37
The remainder is 141 after subtracting 1449 from 1590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

On to step 11:
The number 207 fits into 1410 6 times, leaving a remainder of 168.
Use 6 as the next digit of our solution. 
Result so far: 395573.376
Subtracting 1242 from 1410 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 12:
207 can be fit into 1680 8 times, resulting in a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 395573.3768
If we subtract 1656 from 1680, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
240 divided by 207 is 1 with a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 395573.37681
If we take 207 away from 240, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 14:
If we divide 330 by 207, we get 1 and a remainder of 123.
The next digit of our result is 1. 
Result so far: 395573.376811
Subtract 207 from 330 to get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

The final result is 395573.376811 with a remainder of 1.23e-05.
