We look at the division of 79434240 by 897 
The aim is to understand the frequency of 897 in 79434240.

Moving on to step 1:
If we divide 7 by 897, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 897

Let's proceed to step 2:
If we divide 79 by 897, we get 0 and a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Bring next digit (4) of the dividend behind the 79 and repeat the process: 794 / 897

Let's proceed to step 3:
794 divided by 897 is 0 with a remainder of 794.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 794 to get 794.
Grab the next digit (3) from the dividend, add it to 794, then carry on: 7943 / 897

Step 4:
897 goes into 7943 8 times with a remainder of 767.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 7176 from 7943 leaves us with 767.
Take the next digit (4) from the dividend and append it to 767, then repeat: 7674 / 897

Step 5:
The number 897 fits into 7674 8 times, leaving a remainder of 498.
Write down 8 as next digit of the result. 
Result so far: 88.0
Subtracting 7176 from 7674 leaves us with 498.
Bring next digit (2) of the dividend behind the 498 and repeat the process: 4982 / 897

Moving on to step 6:
If we divide 4982 by 897, we get 5 and a remainder of 497.
Use 5 as the next digit of our solution. 
Result so far: 885.0
Subtracting 4485 from 4982 leaves us with 497.
Fetch the next digit (4) from the dividend, attach it to 497 and continue: 4974 / 897

Advancing to step 7:
The number 897 fits into 4974 5 times, leaving a remainder of 489.
The next digit of our result is 5. 
Result so far: 8855.0
If we take 4485 away from 4974, we end up with 489.
Grab the next digit (0) from the dividend, add it to 489, then carry on: 4890 / 897

Going ahead to step 8:
When dividing 4890 by 897, we get 5 with a remainder of 405.
The next digit of our result is 5. 
Result so far: 88555.0
Subtract 4485 from 4890 to get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Going ahead to step 9:
4050 divided by 897 is 4 with a remainder of 462.
The next digit of our result is 4. 
Result so far: 88555.4
If we subtract 3588 from 4050, we get 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Going ahead to step 10:
897 goes into 4620 5 times with a remainder of 135.
Use 5 as the next digit of our solution. 
Result so far: 88555.45
Subtract 4485 from 4620 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 11:
If we divide 1350 by 897, we get 1 and a remainder of 453.
Record the quotient 1 as the next digit in the result. 
Result so far: 88555.451
Subtract 897 from 1350 to get 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Let's proceed to step 12:
The number 897 fits into 4530 5 times, leaving a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 88555.4515
If we subtract 4485 from 4530, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 13:
The number 897 fits into 450 0 times, leaving a remainder of 450.
Put 0 as the next digit of the answer. 
Result so far: 88555.4515
Subtract 0 from 450 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Let's proceed to step 14:
When dividing 4500 by 897, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 88555.451505
Subtract 4485 from 4500 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 15:
897 can be fit into 150 0 times, resulting in a remainder of 150.
The next digit of our result is 0. 
Result so far: 88555.451505
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 16:
897 goes into 1500 1 times with a remainder of 603.
The number 1 becomes the next digit in our result. 
Result so far: 88555.45150501
Subtract 897 from 1500 to get 603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6030, and continue the process.

After the division, we end up with 88555.45150501 and a remainder of 6.03e-07.
