We're dividing 68090596 by 658 
The aim is to understand the frequency of 658 in 68090596.

Going ahead to step 1:
When dividing 6 by 658, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 658

Going ahead to step 2:
658 goes into 68 0 times with a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Bring next digit (0) of the dividend behind the 68 and repeat the process: 680 / 658

Going ahead to step 3:
The number 658 fits into 680 1 times, leaving a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 22 after subtracting 658 from 680.
Bring next digit (9) of the dividend behind the 22 and repeat the process: 229 / 658

On to step 4:
658 can be fit into 229 0 times, resulting in a remainder of 229.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 229 to get 229.
Take the next digit (0) from the dividend and append it to 229, then repeat: 2290 / 658

On to step 5:
If we divide 2290 by 658, we get 3 and a remainder of 316.
Write down 3 as next digit of the result. 
Result so far: 103.0
Deduct 1974 from 2290 and we're left with 316.
Fetch the next digit (5) from the dividend, attach it to 316 and continue: 3165 / 658

Going ahead to step 6:
3165 divided by 658 is 4 with a remainder of 533.
Use 4 as the next digit of our solution. 
Result so far: 1034.0
If we subtract 2632 from 3165, we get 533.
Take the next digit (9) from the dividend and append it to 533, then repeat: 5339 / 658

Advancing to step 7:
If we divide 5339 by 658, we get 8 and a remainder of 75.
Write down 8 as next digit of the result. 
Result so far: 10348.0
Subtracting 5264 from 5339 leaves us with 75.
Bring next digit (6) of the dividend behind the 75 and repeat the process: 756 / 658

Let's proceed to step 8:
756 divided by 658 is 1 with a remainder of 98.
Record the quotient 1 as the next digit in the result. 
Result so far: 103481.0
If we take 658 away from 756, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 9:
The number 658 fits into 980 1 times, leaving a remainder of 322.
The next digit of our result is 1. 
Result so far: 103481.1
The remainder is 322 after subtracting 658 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Moving on to step 10:
When dividing 3220 by 658, we get 4 with a remainder of 588.
The number 4 becomes the next digit in our result. 
Result so far: 103481.14
Deduct 2632 from 3220 and we're left with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Advancing to step 11:
When dividing 5880 by 658, we get 8 with a remainder of 616.
Record the quotient 8 as the next digit in the result. 
Result so far: 103481.148
Deduct 5264 from 5880 and we're left with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Step 12:
658 goes into 6160 9 times with a remainder of 238.
Record the quotient 9 as the next digit in the result. 
Result so far: 103481.1489
Deduct 5922 from 6160 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Going ahead to step 13:
If we divide 2380 by 658, we get 3 and a remainder of 406.
Use 3 as the next digit of our solution. 
Result so far: 103481.14893
Subtract 1974 from 2380 to get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Step 14:
When dividing 4060 by 658, we get 6 with a remainder of 112.
Write down 6 as next digit of the result. 
Result so far: 103481.148936
If we take 3948 away from 4060, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 15:
1120 divided by 658 is 1 with a remainder of 462.
Put 1 as the next digit of the answer. 
Result so far: 103481.1489361
Deduct 658 from 1120 and we're left with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Step 16:
658 can be fit into 4620 7 times, resulting in a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 103481.14893617
Deduct 4606 from 4620 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 103481.14893617 with a remainder of 1.4e-08.
