We're dividing 16111937 by 658 
The aim is to understand the frequency of 658 in 16111937.

Moving on to step 1:
1 divided by 658 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 658

Let's proceed to step 2:
16 divided by 658 is 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Append the next digit (1) from the dividend to 16 and continue with: 161 / 658

Let's proceed to step 3:
If we divide 161 by 658, we get 0 and a remainder of 161.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 161, we get 161.
Bring next digit (1) of the dividend behind the 161 and repeat the process: 1611 / 658

On to step 4:
1611 divided by 658 is 2 with a remainder of 295.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 1316 from 1611 and we're left with 295.
Take the next digit (1) from the dividend and append it to 295, then repeat: 2951 / 658

Let's proceed to step 5:
658 goes into 2951 4 times with a remainder of 319.
The next digit of our result is 4. 
Result so far: 24.0
Subtract 2632 from 2951 to get 319.
Bring next digit (9) of the dividend behind the 319 and repeat the process: 3199 / 658

Going ahead to step 6:
The number 658 fits into 3199 4 times, leaving a remainder of 567.
Use 4 as the next digit of our solution. 
Result so far: 244.0
Subtract 2632 from 3199 to get 567.
Bring next digit (3) of the dividend behind the 567 and repeat the process: 5673 / 658

Going ahead to step 7:
658 can be fit into 5673 8 times, resulting in a remainder of 409.
Use 8 as the next digit of our solution. 
Result so far: 2448.0
Subtract 5264 from 5673 to get 409.
Append the next digit (7) from the dividend to 409 and continue with: 4097 / 658

On to step 8:
658 can be fit into 4097 6 times, resulting in a remainder of 149.
Put 6 as the next digit of the answer. 
Result so far: 24486.0
The remainder is 149 after subtracting 3948 from 4097.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Going ahead to step 9:
658 goes into 1490 2 times with a remainder of 174.
Put 2 as the next digit of the answer. 
Result so far: 24486.2
Subtract 1316 from 1490 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 10:
1740 divided by 658 is 2 with a remainder of 424.
Record the quotient 2 as the next digit in the result. 
Result so far: 24486.22
Subtracting 1316 from 1740 leaves us with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

After the division, we end up with 24486.22 and a remainder of 0.424.
