91621489 ÷ 297 
The aim is to understand the frequency of 297 in 91621489.

Step 1:
297 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 297

Moving on to step 2:
297 goes into 91 0 times with a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Take the next digit (6) from the dividend and append it to 91, then repeat: 916 / 297

On to step 3:
916 divided by 297 is 3 with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 891 away from 916, we end up with 25.
Append the next digit (2) from the dividend to 25 and continue with: 252 / 297

Let's proceed to step 4:
252 divided by 297 is 0 with a remainder of 252.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Subtracting 0 from 252 leaves us with 252.
Grab the next digit (1) from the dividend, add it to 252, then carry on: 2521 / 297

Going ahead to step 5:
When dividing 2521 by 297, we get 8 with a remainder of 145.
Put 8 as the next digit of the answer. 
Result so far: 308.0
Subtract 2376 from 2521 to get 145.
Append the next digit (4) from the dividend to 145 and continue with: 1454 / 297

Moving on to step 6:
297 can be fit into 1454 4 times, resulting in a remainder of 266.
Put 4 as the next digit of the answer. 
Result so far: 3084.0
If we subtract 1188 from 1454, we get 266.
Grab the next digit (8) from the dividend, add it to 266, then carry on: 2668 / 297

On to step 7:
2668 divided by 297 is 8 with a remainder of 292.
Write down 8 as next digit of the result. 
Result so far: 30848.0
The remainder is 292 after subtracting 2376 from 2668.
Fetch the next digit (9) from the dividend, attach it to 292 and continue: 2929 / 297

Going ahead to step 8:
2929 divided by 297 is 9 with a remainder of 256.
Write down 9 as next digit of the result. 
Result so far: 308489.0
If we take 2673 away from 2929, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 9:
297 can be fit into 2560 8 times, resulting in a remainder of 184.
Write down 8 as next digit of the result. 
Result so far: 308489.8
If we subtract 2376 from 2560, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 10:
1840 divided by 297 is 6 with a remainder of 58.
The next digit of our result is 6. 
Result so far: 308489.86
Subtract 1782 from 1840 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 11:
The number 297 fits into 580 1 times, leaving a remainder of 283.
Record the quotient 1 as the next digit in the result. 
Result so far: 308489.861
If we take 297 away from 580, we end up with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Step 12:
2830 divided by 297 is 9 with a remainder of 157.
Put 9 as the next digit of the answer. 
Result so far: 308489.8619
Deduct 2673 from 2830 and we're left with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

On to step 13:
1570 divided by 297 is 5 with a remainder of 85.
The next digit of our result is 5. 
Result so far: 308489.86195
Subtract 1485 from 1570 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 14:
When dividing 850 by 297, we get 2 with a remainder of 256.
Write down 2 as next digit of the result. 
Result so far: 308489.861952
Subtracting 594 from 850 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 15:
297 goes into 2560 8 times with a remainder of 184.
The next digit of our result is 8. 
Result so far: 308489.8619528
Deduct 2376 from 2560 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 16:
1840 divided by 297 is 6 with a remainder of 58.
Put 6 as the next digit of the answer. 
Result so far: 308489.86195286
Subtract 1782 from 1840 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Our division results in 308489.86195286 with a remaining 5.8e-08.
