Let's divide 83897778 by 658
The aim is to understand the frequency of 658 in 83897778.

Let's proceed to step 1:
658 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 658

Step 2:
658 goes into 83 0 times with a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 83 and we're left with 83.
Take the next digit (8) from the dividend and append it to 83, then repeat: 838 / 658

On to step 3:
658 goes into 838 1 times with a remainder of 180.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 658 away from 838, we end up with 180.
Append the next digit (9) from the dividend to 180 and continue with: 1809 / 658

Moving on to step 4:
658 can be fit into 1809 2 times, resulting in a remainder of 493.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 1316 from 1809, we get 493.
Fetch the next digit (7) from the dividend, attach it to 493 and continue: 4937 / 658

Advancing to step 5:
When dividing 4937 by 658, we get 7 with a remainder of 331.
Use 7 as the next digit of our solution. 
Result so far: 127.0
If we subtract 4606 from 4937, we get 331.
Include the next digit (7) from the dividend after 331, then repeat: 3317 / 658

Let's proceed to step 6:
If we divide 3317 by 658, we get 5 and a remainder of 27.
Put 5 as the next digit of the answer. 
Result so far: 1275.0
Deduct 3290 from 3317 and we're left with 27.
Append the next digit (7) from the dividend to 27 and continue with: 277 / 658

Advancing to step 7:
When dividing 277 by 658, we get 0 with a remainder of 277.
Record the quotient 0 as the next digit in the result. 
Result so far: 12750.0
Deduct 0 from 277 and we're left with 277.
Append the next digit (8) from the dividend to 277 and continue with: 2778 / 658

Moving on to step 8:
When dividing 2778 by 658, we get 4 with a remainder of 146.
Use 4 as the next digit of our solution. 
Result so far: 127504.0
Subtract 2632 from 2778 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

On to step 9:
658 goes into 1460 2 times with a remainder of 144.
Record the quotient 2 as the next digit in the result. 
Result so far: 127504.2
Subtract 1316 from 1460 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 10:
When dividing 1440 by 658, we get 2 with a remainder of 124.
Record the quotient 2 as the next digit in the result. 
Result so far: 127504.22
Subtract 1316 from 1440 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

After the division, we end up with 127504.22 and a remainder of 0.124.
