We look at the division of 3391240 by 694 
The aim is to understand the frequency of 694 in 3391240.

Step 1:
When dividing 3 by 694, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 694

Going ahead to step 2:
When dividing 33 by 694, we get 0 with a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 33 after subtracting 0 from 33.
Grab the next digit (9) from the dividend, add it to 33, then carry on: 339 / 694

Moving on to step 3:
When dividing 339 by 694, we get 0 with a remainder of 339.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 339 to get 339.
Fetch the next digit (1) from the dividend, attach it to 339 and continue: 3391 / 694

Advancing to step 4:
If we divide 3391 by 694, we get 4 and a remainder of 615.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 2776 from 3391, we get 615.
Bring next digit (2) of the dividend behind the 615 and repeat the process: 6152 / 694

Let's proceed to step 5:
The number 694 fits into 6152 8 times, leaving a remainder of 600.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
If we take 5552 away from 6152, we end up with 600.
Fetch the next digit (4) from the dividend, attach it to 600 and continue: 6004 / 694

Going ahead to step 6:
694 can be fit into 6004 8 times, resulting in a remainder of 452.
Write down 8 as next digit of the result. 
Result so far: 488.0
The remainder is 452 after subtracting 5552 from 6004.
Bring next digit (0) of the dividend behind the 452 and repeat the process: 4520 / 694

On to step 7:
694 can be fit into 4520 6 times, resulting in a remainder of 356.
Use 6 as the next digit of our solution. 
Result so far: 4886.0
Subtract 4164 from 4520 to get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Let's proceed to step 8:
694 goes into 3560 5 times with a remainder of 90.
The number 5 becomes the next digit in our result. 
Result so far: 4886.5
If we take 3470 away from 3560, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 9:
694 goes into 900 1 times with a remainder of 206.
Use 1 as the next digit of our solution. 
Result so far: 4886.51
The remainder is 206 after subtracting 694 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Moving on to step 10:
When dividing 2060 by 694, we get 2 with a remainder of 672.
The number 2 becomes the next digit in our result. 
Result so far: 4886.512
Subtracting 1388 from 2060 leaves us with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Advancing to step 11:
694 goes into 6720 9 times with a remainder of 474.
The next digit of our result is 9. 
Result so far: 4886.5129
If we take 6246 away from 6720, we end up with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Advancing to step 12:
The number 694 fits into 4740 6 times, leaving a remainder of 576.
The next digit of our result is 6. 
Result so far: 4886.51296
Subtracting 4164 from 4740 leaves us with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Advancing to step 13:
If we divide 5760 by 694, we get 8 and a remainder of 208.
Put 8 as the next digit of the answer. 
Result so far: 4886.512968
If we take 5552 away from 5760, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

On to step 14:
When dividing 2080 by 694, we get 2 with a remainder of 692.
The next digit of our result is 2. 
Result so far: 4886.5129682
Deduct 1388 from 2080 and we're left with 692.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

Advancing to step 15:
If we divide 6920 by 694, we get 9 and a remainder of 674.
Put 9 as the next digit of the answer. 
Result so far: 4886.51296829
Deduct 6246 from 6920 and we're left with 674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6740, and continue the process.

The final result is 4886.51296829 with a remainder of 6.74e-07.
