We're dividing 5490732 by 897 
The aim is to understand the frequency of 897 in 5490732.

On to step 1:
When dividing 5 by 897, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 897

On to step 2:
When dividing 54 by 897, we get 0 with a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Include the next digit (9) from the dividend after 54, then repeat: 549 / 897

On to step 3:
897 can be fit into 549 0 times, resulting in a remainder of 549.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 549 after subtracting 0 from 549.
Bring next digit (0) of the dividend behind the 549 and repeat the process: 5490 / 897

Going ahead to step 4:
897 can be fit into 5490 6 times, resulting in a remainder of 108.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 5382 from 5490 and we're left with 108.
Bring next digit (7) of the dividend behind the 108 and repeat the process: 1087 / 897

Let's proceed to step 5:
897 can be fit into 1087 1 times, resulting in a remainder of 190.
Write down 1 as next digit of the result. 
Result so far: 61.0
If we subtract 897 from 1087, we get 190.
Grab the next digit (3) from the dividend, add it to 190, then carry on: 1903 / 897

Advancing to step 6:
897 goes into 1903 2 times with a remainder of 109.
The number 2 becomes the next digit in our result. 
Result so far: 612.0
The remainder is 109 after subtracting 1794 from 1903.
Take the next digit (2) from the dividend and append it to 109, then repeat: 1092 / 897

Moving on to step 7:
If we divide 1092 by 897, we get 1 and a remainder of 195.
Record the quotient 1 as the next digit in the result. 
Result so far: 6121.0
Subtract 897 from 1092 to get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

On to step 8:
The number 897 fits into 1950 2 times, leaving a remainder of 156.
Use 2 as the next digit of our solution. 
Result so far: 6121.2
The remainder is 156 after subtracting 1794 from 1950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 9:
897 can be fit into 1560 1 times, resulting in a remainder of 663.
Write down 1 as next digit of the result. 
Result so far: 6121.21
If we subtract 897 from 1560, we get 663.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

Moving on to step 10:
When dividing 6630 by 897, we get 7 with a remainder of 351.
Put 7 as the next digit of the answer. 
Result so far: 6121.217
If we subtract 6279 from 6630, we get 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

On to step 11:
897 can be fit into 3510 3 times, resulting in a remainder of 819.
Write down 3 as next digit of the result. 
Result so far: 6121.2173
If we take 2691 away from 3510, we end up with 819.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8190, and continue the process.

On to step 12:
897 goes into 8190 9 times with a remainder of 117.
Write down 9 as next digit of the result. 
Result so far: 6121.21739
If we subtract 8073 from 8190, we get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

On to step 13:
The number 897 fits into 1170 1 times, leaving a remainder of 273.
Record the quotient 1 as the next digit in the result. 
Result so far: 6121.217391
The remainder is 273 after subtracting 897 from 1170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Going ahead to step 14:
897 goes into 2730 3 times with a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 6121.2173913
If we take 2691 away from 2730, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 15:
897 can be fit into 390 0 times, resulting in a remainder of 390.
Put 0 as the next digit of the answer. 
Result so far: 6121.2173913
Subtract 0 from 390 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

After the division, we end up with 6121.2173913 and a remainder of 3.9e-07.
