63529969 ÷ 653 
The aim is to understand the frequency of 653 in 63529969.

Step 1:
The number 653 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 653

Going ahead to step 2:
653 can be fit into 63 0 times, resulting in a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Bring next digit (5) of the dividend behind the 63 and repeat the process: 635 / 653

Moving on to step 3:
653 goes into 635 0 times with a remainder of 635.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 635 and we're left with 635.
Take the next digit (2) from the dividend and append it to 635, then repeat: 6352 / 653

Going ahead to step 4:
653 can be fit into 6352 9 times, resulting in a remainder of 475.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 5877 away from 6352, we end up with 475.
Take the next digit (9) from the dividend and append it to 475, then repeat: 4759 / 653

Step 5:
653 can be fit into 4759 7 times, resulting in a remainder of 188.
The next digit of our result is 7. 
Result so far: 97.0
The remainder is 188 after subtracting 4571 from 4759.
Grab the next digit (9) from the dividend, add it to 188, then carry on: 1889 / 653

Going ahead to step 6:
653 can be fit into 1889 2 times, resulting in a remainder of 583.
Use 2 as the next digit of our solution. 
Result so far: 972.0
Subtract 1306 from 1889 to get 583.
Include the next digit (6) from the dividend after 583, then repeat: 5836 / 653

Advancing to step 7:
When dividing 5836 by 653, we get 8 with a remainder of 612.
Record the quotient 8 as the next digit in the result. 
Result so far: 9728.0
If we subtract 5224 from 5836, we get 612.
Grab the next digit (9) from the dividend, add it to 612, then carry on: 6129 / 653

Let's proceed to step 8:
653 goes into 6129 9 times with a remainder of 252.
The number 9 becomes the next digit in our result. 
Result so far: 97289.0
Deduct 5877 from 6129 and we're left with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Step 9:
The number 653 fits into 2520 3 times, leaving a remainder of 561.
Put 3 as the next digit of the answer. 
Result so far: 97289.3
The remainder is 561 after subtracting 1959 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

On to step 10:
If we divide 5610 by 653, we get 8 and a remainder of 386.
Write down 8 as next digit of the result. 
Result so far: 97289.38
The remainder is 386 after subtracting 5224 from 5610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

On to step 11:
3860 divided by 653 is 5 with a remainder of 595.
Put 5 as the next digit of the answer. 
Result so far: 97289.385
Subtracting 3265 from 3860 leaves us with 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Let's proceed to step 12:
653 goes into 5950 9 times with a remainder of 73.
The number 9 becomes the next digit in our result. 
Result so far: 97289.3859
The remainder is 73 after subtracting 5877 from 5950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 13:
When dividing 730 by 653, we get 1 with a remainder of 77.
The next digit of our result is 1. 
Result so far: 97289.38591
The remainder is 77 after subtracting 653 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 14:
When dividing 770 by 653, we get 1 with a remainder of 117.
Write down 1 as next digit of the result. 
Result so far: 97289.385911
Deduct 653 from 770 and we're left with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

After the division, we end up with 97289.385911 and a remainder of 1.17e-05.
