We're dividing 56078531 by 690 
The aim is to understand the frequency of 690 in 56078531.

On to step 1:
When dividing 5 by 690, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 690

Advancing to step 2:
56 divided by 690 is 0 with a remainder of 56.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 56 and we're left with 56.
Grab the next digit (0) from the dividend, add it to 56, then carry on: 560 / 690

On to step 3:
The number 690 fits into 560 0 times, leaving a remainder of 560.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 560 and we're left with 560.
Fetch the next digit (7) from the dividend, attach it to 560 and continue: 5607 / 690

Step 4:
5607 divided by 690 is 8 with a remainder of 87.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 5520 from 5607 to get 87.
Include the next digit (8) from the dividend after 87, then repeat: 878 / 690

Let's proceed to step 5:
When dividing 878 by 690, we get 1 with a remainder of 188.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
Subtract 690 from 878 to get 188.
Append the next digit (5) from the dividend to 188 and continue with: 1885 / 690

Moving on to step 6:
1885 divided by 690 is 2 with a remainder of 505.
Put 2 as the next digit of the answer. 
Result so far: 812.0
If we take 1380 away from 1885, we end up with 505.
Take the next digit (3) from the dividend and append it to 505, then repeat: 5053 / 690

On to step 7:
If we divide 5053 by 690, we get 7 and a remainder of 223.
The number 7 becomes the next digit in our result. 
Result so far: 8127.0
Deduct 4830 from 5053 and we're left with 223.
Include the next digit (1) from the dividend after 223, then repeat: 2231 / 690

Going ahead to step 8:
If we divide 2231 by 690, we get 3 and a remainder of 161.
Put 3 as the next digit of the answer. 
Result so far: 81273.0
If we subtract 2070 from 2231, we get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Let's proceed to step 9:
1610 divided by 690 is 2 with a remainder of 230.
The number 2 becomes the next digit in our result. 
Result so far: 81273.2
If we take 1380 away from 1610, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 10:
2300 divided by 690 is 3 with a remainder of 230.
The number 3 becomes the next digit in our result. 
Result so far: 81273.23
Subtracting 2070 from 2300 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 11:
If we divide 2300 by 690, we get 3 and a remainder of 230.
Put 3 as the next digit of the answer. 
Result so far: 81273.233
If we take 2070 away from 2300, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

The quotient of the division is 81273.233, and the remainder is 0.023.
