We're dividing 71655289 by 891 
The aim is to understand the frequency of 891 in 71655289.

Going ahead to step 1:
891 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 891

On to step 2:
891 can be fit into 71 0 times, resulting in a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Bring next digit (6) of the dividend behind the 71 and repeat the process: 716 / 891

Going ahead to step 3:
The number 891 fits into 716 0 times, leaving a remainder of 716.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 716 to get 716.
Bring next digit (5) of the dividend behind the 716 and repeat the process: 7165 / 891

Advancing to step 4:
The number 891 fits into 7165 8 times, leaving a remainder of 37.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 7128 from 7165 and we're left with 37.
Bring next digit (5) of the dividend behind the 37 and repeat the process: 375 / 891

Advancing to step 5:
If we divide 375 by 891, we get 0 and a remainder of 375.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
Subtract 0 from 375 to get 375.
Grab the next digit (2) from the dividend, add it to 375, then carry on: 3752 / 891

Step 6:
891 can be fit into 3752 4 times, resulting in a remainder of 188.
Write down 4 as next digit of the result. 
Result so far: 804.0
Subtracting 3564 from 3752 leaves us with 188.
Append the next digit (8) from the dividend to 188 and continue with: 1888 / 891

Going ahead to step 7:
1888 divided by 891 is 2 with a remainder of 106.
Put 2 as the next digit of the answer. 
Result so far: 8042.0
Deduct 1782 from 1888 and we're left with 106.
Take the next digit (9) from the dividend and append it to 106, then repeat: 1069 / 891

Let's proceed to step 8:
891 can be fit into 1069 1 times, resulting in a remainder of 178.
The number 1 becomes the next digit in our result. 
Result so far: 80421.0
Subtract 891 from 1069 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 9:
1780 divided by 891 is 1 with a remainder of 889.
The next digit of our result is 1. 
Result so far: 80421.1
Deduct 891 from 1780 and we're left with 889.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8890, and continue the process.

Advancing to step 10:
The number 891 fits into 8890 9 times, leaving a remainder of 871.
Put 9 as the next digit of the answer. 
Result so far: 80421.19
Subtracting 8019 from 8890 leaves us with 871.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8710, and continue the process.

Moving on to step 11:
891 goes into 8710 9 times with a remainder of 691.
Put 9 as the next digit of the answer. 
Result so far: 80421.199
Subtract 8019 from 8710 to get 691.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6910, and continue the process.

The final result is 80421.199 with a remainder of 0.0691.
