We're dividing 71072600 by 657 
The aim is to understand the frequency of 657 in 71072600.

Advancing to step 1:
If we divide 7 by 657, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 657

Step 2:
657 goes into 71 0 times with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Fetch the next digit (0) from the dividend, attach it to 71 and continue: 710 / 657

Step 3:
The number 657 fits into 710 1 times, leaving a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 657 from 710 and we're left with 53.
Bring next digit (7) of the dividend behind the 53 and repeat the process: 537 / 657

Advancing to step 4:
537 divided by 657 is 0 with a remainder of 537.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 537 and we're left with 537.
Fetch the next digit (2) from the dividend, attach it to 537 and continue: 5372 / 657

Moving on to step 5:
5372 divided by 657 is 8 with a remainder of 116.
The next digit of our result is 8. 
Result so far: 108.0
If we take 5256 away from 5372, we end up with 116.
Grab the next digit (6) from the dividend, add it to 116, then carry on: 1166 / 657

Going ahead to step 6:
657 can be fit into 1166 1 times, resulting in a remainder of 509.
Record the quotient 1 as the next digit in the result. 
Result so far: 1081.0
The remainder is 509 after subtracting 657 from 1166.
Fetch the next digit (0) from the dividend, attach it to 509 and continue: 5090 / 657

Step 7:
5090 divided by 657 is 7 with a remainder of 491.
The next digit of our result is 7. 
Result so far: 10817.0
The remainder is 491 after subtracting 4599 from 5090.
Include the next digit (0) from the dividend after 491, then repeat: 4910 / 657

Let's proceed to step 8:
657 goes into 4910 7 times with a remainder of 311.
Record the quotient 7 as the next digit in the result. 
Result so far: 108177.0
Subtract 4599 from 4910 to get 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

On to step 9:
When dividing 3110 by 657, we get 4 with a remainder of 482.
Record the quotient 4 as the next digit in the result. 
Result so far: 108177.4
Subtracting 2628 from 3110 leaves us with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Going ahead to step 10:
The number 657 fits into 4820 7 times, leaving a remainder of 221.
Record the quotient 7 as the next digit in the result. 
Result so far: 108177.47
The remainder is 221 after subtracting 4599 from 4820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Going ahead to step 11:
When dividing 2210 by 657, we get 3 with a remainder of 239.
The next digit of our result is 3. 
Result so far: 108177.473
Subtract 1971 from 2210 to get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Let's proceed to step 12:
657 goes into 2390 3 times with a remainder of 419.
Write down 3 as next digit of the result. 
Result so far: 108177.4733
Subtracting 1971 from 2390 leaves us with 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

The final outcome is 108177.4733, with a leftover of 0.00419.
