We divide 311581 by 97
The aim is to understand the frequency of 97 in 311581.

Step 1:
The number 97 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 97

Moving on to step 2:
31 divided by 97 is 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Take the next digit (1) from the dividend and append it to 31, then repeat: 311 / 97

Advancing to step 3:
The number 97 fits into 311 3 times, leaving a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 291 from 311 and we're left with 20.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 97

Let's proceed to step 4:
97 can be fit into 205 2 times, resulting in a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
Subtracting 194 from 205 leaves us with 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 97

Step 5:
When dividing 118 by 97, we get 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 321.0
If we subtract 97 from 118, we get 21.
Fetch the next digit (1) from the dividend, attach it to 21 and continue: 211 / 97

Advancing to step 6:
97 can be fit into 211 2 times, resulting in a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 3212.0
The remainder is 17 after subtracting 194 from 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
97 can be fit into 170 1 times, resulting in a remainder of 73.
Use 1 as the next digit of our solution. 
Result so far: 3212.1
Subtract 97 from 170 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 8:
If we divide 730 by 97, we get 7 and a remainder of 51.
Record the quotient 7 as the next digit in the result. 
Result so far: 3212.17
Subtracting 679 from 730 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 9:
97 can be fit into 510 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 3212.175
The remainder is 25 after subtracting 485 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 10:
250 divided by 97 is 2 with a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 3212.1752
Subtracting 194 from 250 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 11:
When dividing 560 by 97, we get 5 with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 3212.17525
Subtract 485 from 560 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 12:
97 can be fit into 750 7 times, resulting in a remainder of 71.
Use 7 as the next digit of our solution. 
Result so far: 3212.175257
Deduct 679 from 750 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 13:
97 can be fit into 710 7 times, resulting in a remainder of 31.
The next digit of our result is 7. 
Result so far: 3212.1752577
Deduct 679 from 710 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The quotient of the division is 3212.1752577, and the remainder is 3.1e-07.
