We look at the division of 76981612 by 653 
The aim is to understand the frequency of 653 in 76981612.

Advancing to step 1:
When dividing 7 by 653, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 653

Let's proceed to step 2:
76 divided by 653 is 0 with a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 76, we end up with 76.
Include the next digit (9) from the dividend after 76, then repeat: 769 / 653

Moving on to step 3:
769 divided by 653 is 1 with a remainder of 116.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 653 from 769 to get 116.
Fetch the next digit (8) from the dividend, attach it to 116 and continue: 1168 / 653

On to step 4:
653 goes into 1168 1 times with a remainder of 515.
The next digit of our result is 1. 
Result so far: 11.0
If we take 653 away from 1168, we end up with 515.
Include the next digit (1) from the dividend after 515, then repeat: 5151 / 653

Moving on to step 5:
653 goes into 5151 7 times with a remainder of 580.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
Subtracting 4571 from 5151 leaves us with 580.
Bring next digit (6) of the dividend behind the 580 and repeat the process: 5806 / 653

Advancing to step 6:
653 goes into 5806 8 times with a remainder of 582.
The number 8 becomes the next digit in our result. 
Result so far: 1178.0
If we subtract 5224 from 5806, we get 582.
Fetch the next digit (1) from the dividend, attach it to 582 and continue: 5821 / 653

Step 7:
653 can be fit into 5821 8 times, resulting in a remainder of 597.
Record the quotient 8 as the next digit in the result. 
Result so far: 11788.0
If we subtract 5224 from 5821, we get 597.
Take the next digit (2) from the dividend and append it to 597, then repeat: 5972 / 653

Step 8:
653 goes into 5972 9 times with a remainder of 95.
The next digit of our result is 9. 
Result so far: 117889.0
If we subtract 5877 from 5972, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 9:
If we divide 950 by 653, we get 1 and a remainder of 297.
Use 1 as the next digit of our solution. 
Result so far: 117889.1
The remainder is 297 after subtracting 653 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Moving on to step 10:
If we divide 2970 by 653, we get 4 and a remainder of 358.
Put 4 as the next digit of the answer. 
Result so far: 117889.14
If we subtract 2612 from 2970, we get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Advancing to step 11:
If we divide 3580 by 653, we get 5 and a remainder of 315.
The next digit of our result is 5. 
Result so far: 117889.145
Deduct 3265 from 3580 and we're left with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Let's proceed to step 12:
653 goes into 3150 4 times with a remainder of 538.
Put 4 as the next digit of the answer. 
Result so far: 117889.1454
Subtract 2612 from 3150 to get 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Step 13:
The number 653 fits into 5380 8 times, leaving a remainder of 156.
Record the quotient 8 as the next digit in the result. 
Result so far: 117889.14548
If we take 5224 away from 5380, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 14:
653 goes into 1560 2 times with a remainder of 254.
Use 2 as the next digit of our solution. 
Result so far: 117889.145482
Subtract 1306 from 1560 to get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Step 15:
When dividing 2540 by 653, we get 3 with a remainder of 581.
Use 3 as the next digit of our solution. 
Result so far: 117889.1454823
If we take 1959 away from 2540, we end up with 581.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

Moving on to step 16:
If we divide 5810 by 653, we get 8 and a remainder of 586.
The number 8 becomes the next digit in our result. 
Result so far: 117889.14548238
Deduct 5224 from 5810 and we're left with 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Our division results in 117889.14548238 with a remaining 5.86e-07.
