78397554 ÷ 693 
The aim is to understand the frequency of 693 in 78397554.

Moving on to step 1:
When dividing 7 by 693, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 693

Let's proceed to step 2:
693 goes into 78 0 times with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Bring next digit (3) of the dividend behind the 78 and repeat the process: 783 / 693

Advancing to step 3:
When dividing 783 by 693, we get 1 with a remainder of 90.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 693 from 783 to get 90.
Append the next digit (9) from the dividend to 90 and continue with: 909 / 693

Moving on to step 4:
693 can be fit into 909 1 times, resulting in a remainder of 216.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 216 after subtracting 693 from 909.
Include the next digit (7) from the dividend after 216, then repeat: 2167 / 693

On to step 5:
If we divide 2167 by 693, we get 3 and a remainder of 88.
Record the quotient 3 as the next digit in the result. 
Result so far: 113.0
Subtracting 2079 from 2167 leaves us with 88.
Fetch the next digit (5) from the dividend, attach it to 88 and continue: 885 / 693

Advancing to step 6:
693 can be fit into 885 1 times, resulting in a remainder of 192.
Use 1 as the next digit of our solution. 
Result so far: 1131.0
Subtract 693 from 885 to get 192.
Fetch the next digit (5) from the dividend, attach it to 192 and continue: 1925 / 693

Advancing to step 7:
The number 693 fits into 1925 2 times, leaving a remainder of 539.
Record the quotient 2 as the next digit in the result. 
Result so far: 11312.0
If we take 1386 away from 1925, we end up with 539.
Take the next digit (4) from the dividend and append it to 539, then repeat: 5394 / 693

Advancing to step 8:
When dividing 5394 by 693, we get 7 with a remainder of 543.
The number 7 becomes the next digit in our result. 
Result so far: 113127.0
Deduct 4851 from 5394 and we're left with 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

Step 9:
When dividing 5430 by 693, we get 7 with a remainder of 579.
Use 7 as the next digit of our solution. 
Result so far: 113127.7
Subtract 4851 from 5430 to get 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

Step 10:
The number 693 fits into 5790 8 times, leaving a remainder of 246.
Use 8 as the next digit of our solution. 
Result so far: 113127.78
If we subtract 5544 from 5790, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Going ahead to step 11:
693 can be fit into 2460 3 times, resulting in a remainder of 381.
Put 3 as the next digit of the answer. 
Result so far: 113127.783
Subtracting 2079 from 2460 leaves us with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Let's proceed to step 12:
If we divide 3810 by 693, we get 5 and a remainder of 345.
Put 5 as the next digit of the answer. 
Result so far: 113127.7835
Subtracting 3465 from 3810 leaves us with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Advancing to step 13:
When dividing 3450 by 693, we get 4 with a remainder of 678.
The number 4 becomes the next digit in our result. 
Result so far: 113127.78354
Deduct 2772 from 3450 and we're left with 678.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

Moving on to step 14:
If we divide 6780 by 693, we get 9 and a remainder of 543.
Record the quotient 9 as the next digit in the result. 
Result so far: 113127.783549
The remainder is 543 after subtracting 6237 from 6780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

Let's proceed to step 15:
5430 divided by 693 is 7 with a remainder of 579.
Record the quotient 7 as the next digit in the result. 
Result so far: 113127.7835497
Deduct 4851 from 5430 and we're left with 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

On to step 16:
The number 693 fits into 5790 8 times, leaving a remainder of 246.
Use 8 as the next digit of our solution. 
Result so far: 113127.78354978
Subtract 5544 from 5790 to get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

After the division, we end up with 113127.78354978 and a remainder of 2.46e-07.
