We look at the division of 53793290 by 690 
The aim is to understand the frequency of 690 in 53793290.

Advancing to step 1:
If we divide 5 by 690, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 690

Let's proceed to step 2:
When dividing 53 by 690, we get 0 with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Fetch the next digit (7) from the dividend, attach it to 53 and continue: 537 / 690

Let's proceed to step 3:
The number 690 fits into 537 0 times, leaving a remainder of 537.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 537 after subtracting 0 from 537.
Take the next digit (9) from the dividend and append it to 537, then repeat: 5379 / 690

Let's proceed to step 4:
690 goes into 5379 7 times with a remainder of 549.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 4830 from 5379 leaves us with 549.
Take the next digit (3) from the dividend and append it to 549, then repeat: 5493 / 690

Advancing to step 5:
690 can be fit into 5493 7 times, resulting in a remainder of 663.
Put 7 as the next digit of the answer. 
Result so far: 77.0
The remainder is 663 after subtracting 4830 from 5493.
Include the next digit (2) from the dividend after 663, then repeat: 6632 / 690

On to step 6:
If we divide 6632 by 690, we get 9 and a remainder of 422.
Use 9 as the next digit of our solution. 
Result so far: 779.0
If we take 6210 away from 6632, we end up with 422.
Append the next digit (9) from the dividend to 422 and continue with: 4229 / 690

On to step 7:
4229 divided by 690 is 6 with a remainder of 89.
The next digit of our result is 6. 
Result so far: 7796.0
Subtracting 4140 from 4229 leaves us with 89.
Bring next digit (0) of the dividend behind the 89 and repeat the process: 890 / 690

Step 8:
The number 690 fits into 890 1 times, leaving a remainder of 200.
Put 1 as the next digit of the answer. 
Result so far: 77961.0
If we take 690 away from 890, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 9:
690 goes into 2000 2 times with a remainder of 620.
The number 2 becomes the next digit in our result. 
Result so far: 77961.2
Subtract 1380 from 2000 to get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

On to step 10:
690 can be fit into 6200 8 times, resulting in a remainder of 680.
The next digit of our result is 8. 
Result so far: 77961.28
Subtracting 5520 from 6200 leaves us with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Moving on to step 11:
The number 690 fits into 6800 9 times, leaving a remainder of 590.
Use 9 as the next digit of our solution. 
Result so far: 77961.289
Deduct 6210 from 6800 and we're left with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Going ahead to step 12:
If we divide 5900 by 690, we get 8 and a remainder of 380.
The next digit of our result is 8. 
Result so far: 77961.2898
Subtracting 5520 from 5900 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 13:
3800 divided by 690 is 5 with a remainder of 350.
Use 5 as the next digit of our solution. 
Result so far: 77961.28985
Deduct 3450 from 3800 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 14:
690 goes into 3500 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 77961.289855
If we take 3450 away from 3500, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 77961.289855 and a remainder of 5e-06.
