Let's divide 1977521 by 234
The aim is to understand the frequency of 234 in 1977521.

Going ahead to step 1:
The number 234 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 234

Going ahead to step 2:
When dividing 19 by 234, we get 0 with a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Fetch the next digit (7) from the dividend, attach it to 19 and continue: 197 / 234

On to step 3:
234 goes into 197 0 times with a remainder of 197.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 197 leaves us with 197.
Append the next digit (7) from the dividend to 197 and continue with: 1977 / 234

On to step 4:
If we divide 1977 by 234, we get 8 and a remainder of 105.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 1872 from 1977 to get 105.
Take the next digit (5) from the dividend and append it to 105, then repeat: 1055 / 234

Advancing to step 5:
When dividing 1055 by 234, we get 4 with a remainder of 119.
Write down 4 as next digit of the result. 
Result so far: 84.0
Deduct 936 from 1055 and we're left with 119.
Take the next digit (2) from the dividend and append it to 119, then repeat: 1192 / 234

Step 6:
234 goes into 1192 5 times with a remainder of 22.
Use 5 as the next digit of our solution. 
Result so far: 845.0
Subtracting 1170 from 1192 leaves us with 22.
Append the next digit (1) from the dividend to 22 and continue with: 221 / 234

Step 7:
221 divided by 234 is 0 with a remainder of 221.
The next digit of our result is 0. 
Result so far: 8450.0
Deduct 0 from 221 and we're left with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Step 8:
234 can be fit into 2210 9 times, resulting in a remainder of 104.
Record the quotient 9 as the next digit in the result. 
Result so far: 8450.9
Subtract 2106 from 2210 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 9:
234 goes into 1040 4 times with a remainder of 104.
Record the quotient 4 as the next digit in the result. 
Result so far: 8450.94
The remainder is 104 after subtracting 936 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 10:
234 can be fit into 1040 4 times, resulting in a remainder of 104.
Record the quotient 4 as the next digit in the result. 
Result so far: 8450.944
If we take 936 away from 1040, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The final outcome is 8450.944, with a leftover of 0.0104.
