We're dividing 15592860 by 693 
The aim is to understand the frequency of 693 in 15592860.

On to step 1:
693 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 693

Let's proceed to step 2:
The number 693 fits into 15 0 times, leaving a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 693

On to step 3:
If we divide 155 by 693, we get 0 and a remainder of 155.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 155 and we're left with 155.
Grab the next digit (9) from the dividend, add it to 155, then carry on: 1559 / 693

Let's proceed to step 4:
When dividing 1559 by 693, we get 2 with a remainder of 173.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 1386 from 1559 to get 173.
Fetch the next digit (2) from the dividend, attach it to 173 and continue: 1732 / 693

Moving on to step 5:
If we divide 1732 by 693, we get 2 and a remainder of 346.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we take 1386 away from 1732, we end up with 346.
Take the next digit (8) from the dividend and append it to 346, then repeat: 3468 / 693

Step 6:
If we divide 3468 by 693, we get 5 and a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 225.0
If we take 3465 away from 3468, we end up with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 693

Step 7:
If we divide 36 by 693, we get 0 and a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 2250.0
Subtract 0 from 36 to get 36.
Bring next digit (0) of the dividend behind the 36 and repeat the process: 360 / 693

Let's proceed to step 8:
If we divide 360 by 693, we get 0 and a remainder of 360.
Use 0 as the next digit of our solution. 
Result so far: 22500.0
The remainder is 360 after subtracting 0 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 9:
When dividing 3600 by 693, we get 5 with a remainder of 135.
Write down 5 as next digit of the result. 
Result so far: 22500.5
If we take 3465 away from 3600, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 10:
693 can be fit into 1350 1 times, resulting in a remainder of 657.
The next digit of our result is 1. 
Result so far: 22500.51
If we take 693 away from 1350, we end up with 657.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6570, and continue the process.

Going ahead to step 11:
693 can be fit into 6570 9 times, resulting in a remainder of 333.
The next digit of our result is 9. 
Result so far: 22500.519
Subtract 6237 from 6570 to get 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Going ahead to step 12:
693 goes into 3330 4 times with a remainder of 558.
The next digit of our result is 4. 
Result so far: 22500.5194
Subtract 2772 from 3330 to get 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Step 13:
The number 693 fits into 5580 8 times, leaving a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 22500.51948
Deduct 5544 from 5580 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 14:
360 divided by 693 is 0 with a remainder of 360.
Record the quotient 0 as the next digit in the result. 
Result so far: 22500.51948
Subtract 0 from 360 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 15:
3600 divided by 693 is 5 with a remainder of 135.
The number 5 becomes the next digit in our result. 
Result so far: 22500.5194805
Deduct 3465 from 3600 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 16:
1350 divided by 693 is 1 with a remainder of 657.
Use 1 as the next digit of our solution. 
Result so far: 22500.51948051
If we take 693 away from 1350, we end up with 657.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6570, and continue the process.

The final outcome is 22500.51948051, with a leftover of 6.57e-07.
