We divide 831691 by 97
The aim is to understand the frequency of 97 in 831691.

On to step 1:
97 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 97

Advancing to step 2:
If we divide 83 by 97, we get 0 and a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Grab the next digit (1) from the dividend, add it to 83, then carry on: 831 / 97

Advancing to step 3:
The number 97 fits into 831 8 times, leaving a remainder of 55.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 776 from 831 leaves us with 55.
Take the next digit (6) from the dividend and append it to 55, then repeat: 556 / 97

Let's proceed to step 4:
97 can be fit into 556 5 times, resulting in a remainder of 71.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
Subtract 485 from 556 to get 71.
Bring next digit (9) of the dividend behind the 71 and repeat the process: 719 / 97

Going ahead to step 5:
If we divide 719 by 97, we get 7 and a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 857.0
Deduct 679 from 719 and we're left with 40.
Fetch the next digit (1) from the dividend, attach it to 40 and continue: 401 / 97

On to step 6:
97 can be fit into 401 4 times, resulting in a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 8574.0
Subtracting 388 from 401 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
If we divide 130 by 97, we get 1 and a remainder of 33.
The next digit of our result is 1. 
Result so far: 8574.1
If we take 97 away from 130, 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.

Moving on to step 8:
97 goes into 330 3 times with a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 8574.13
Subtract 291 from 330 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 9:
When dividing 390 by 97, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 8574.134
If we subtract 388 from 390, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
When dividing 20 by 97, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 8574.134
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
The number 97 fits into 200 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 8574.13402
The remainder is 6 after subtracting 194 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 12:
97 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 8574.13402
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 13:
97 goes into 600 6 times with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 8574.1340206
Subtracting 582 from 600 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 14:
97 goes into 180 1 times with a remainder of 83.
Use 1 as the next digit of our solution. 
Result so far: 8574.13402061
Deduct 97 from 180 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

The final result is 8574.13402061 with a remainder of 8.3e-08.
