We look at the division of 81870460 by 711 
The aim is to understand the frequency of 711 in 81870460.

Advancing to step 1:
When dividing 8 by 711, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 711

Going ahead to step 2:
When dividing 81 by 711, we get 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Bring next digit (8) of the dividend behind the 81 and repeat the process: 818 / 711

Step 3:
818 divided by 711 is 1 with a remainder of 107.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 711 from 818 leaves us with 107.
Append the next digit (7) from the dividend to 107 and continue with: 1077 / 711

On to step 4:
1077 divided by 711 is 1 with a remainder of 366.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 711 from 1077, we get 366.
Append the next digit (0) from the dividend to 366 and continue with: 3660 / 711

On to step 5:
When dividing 3660 by 711, we get 5 with a remainder of 105.
Write down 5 as next digit of the result. 
Result so far: 115.0
If we subtract 3555 from 3660, we get 105.
Fetch the next digit (4) from the dividend, attach it to 105 and continue: 1054 / 711

Let's proceed to step 6:
The number 711 fits into 1054 1 times, leaving a remainder of 343.
Use 1 as the next digit of our solution. 
Result so far: 1151.0
Subtract 711 from 1054 to get 343.
Grab the next digit (6) from the dividend, add it to 343, then carry on: 3436 / 711

Let's proceed to step 7:
The number 711 fits into 3436 4 times, leaving a remainder of 592.
Record the quotient 4 as the next digit in the result. 
Result so far: 11514.0
If we take 2844 away from 3436, we end up with 592.
Append the next digit (0) from the dividend to 592 and continue with: 5920 / 711

Moving on to step 8:
If we divide 5920 by 711, we get 8 and a remainder of 232.
The number 8 becomes the next digit in our result. 
Result so far: 115148.0
If we subtract 5688 from 5920, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

On to step 9:
When dividing 2320 by 711, we get 3 with a remainder of 187.
Use 3 as the next digit of our solution. 
Result so far: 115148.3
Subtracting 2133 from 2320 leaves us with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Moving on to step 10:
When dividing 1870 by 711, we get 2 with a remainder of 448.
Use 2 as the next digit of our solution. 
Result so far: 115148.32
The remainder is 448 after subtracting 1422 from 1870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Step 11:
If we divide 4480 by 711, we get 6 and a remainder of 214.
Put 6 as the next digit of the answer. 
Result so far: 115148.326
Subtracting 4266 from 4480 leaves us with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

On to step 12:
2140 divided by 711 is 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 115148.3263
Subtracting 2133 from 2140 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 13:
711 can be fit into 70 0 times, resulting in a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 115148.3263
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 14:
711 can be fit into 700 0 times, resulting in a remainder of 700.
The number 0 becomes the next digit in our result. 
Result so far: 115148.3263
The remainder is 700 after subtracting 0 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

The final outcome is 115148.3263, with a leftover of 7e-05.
