Let's divide 61399521 by 699
The aim is to understand the frequency of 699 in 61399521.

Let's proceed to step 1:
When dividing 6 by 699, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 699

Advancing to step 2:
699 goes into 61 0 times with a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 61, we end up with 61.
Grab the next digit (3) from the dividend, add it to 61, then carry on: 613 / 699

Moving on to step 3:
699 goes into 613 0 times with a remainder of 613.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 613, we get 613.
Bring next digit (9) of the dividend behind the 613 and repeat the process: 6139 / 699

Step 4:
699 goes into 6139 8 times with a remainder of 547.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 547 after subtracting 5592 from 6139.
Append the next digit (9) from the dividend to 547 and continue with: 5479 / 699

Step 5:
When dividing 5479 by 699, we get 7 with a remainder of 586.
Put 7 as the next digit of the answer. 
Result so far: 87.0
Deduct 4893 from 5479 and we're left with 586.
Include the next digit (5) from the dividend after 586, then repeat: 5865 / 699

Going ahead to step 6:
5865 divided by 699 is 8 with a remainder of 273.
The next digit of our result is 8. 
Result so far: 878.0
If we subtract 5592 from 5865, we get 273.
Grab the next digit (2) from the dividend, add it to 273, then carry on: 2732 / 699

Let's proceed to step 7:
2732 divided by 699 is 3 with a remainder of 635.
Use 3 as the next digit of our solution. 
Result so far: 8783.0
If we subtract 2097 from 2732, we get 635.
Take the next digit (1) from the dividend and append it to 635, then repeat: 6351 / 699

Advancing to step 8:
699 goes into 6351 9 times with a remainder of 60.
The number 9 becomes the next digit in our result. 
Result so far: 87839.0
Deduct 6291 from 6351 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
699 can be fit into 600 0 times, resulting in a remainder of 600.
Write down 0 as next digit of the result. 
Result so far: 87839.0
Subtracting 0 from 600 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 10:
If we divide 6000 by 699, we get 8 and a remainder of 408.
Write down 8 as next digit of the result. 
Result so far: 87839.08
If we take 5592 away from 6000, we end up with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Let's proceed to step 11:
The number 699 fits into 4080 5 times, leaving a remainder of 585.
Put 5 as the next digit of the answer. 
Result so far: 87839.085
The remainder is 585 after subtracting 3495 from 4080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Let's proceed to step 12:
The number 699 fits into 5850 8 times, leaving a remainder of 258.
Write down 8 as next digit of the result. 
Result so far: 87839.0858
Subtract 5592 from 5850 to get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Let's proceed to step 13:
The number 699 fits into 2580 3 times, leaving a remainder of 483.
Put 3 as the next digit of the answer. 
Result so far: 87839.08583
If we subtract 2097 from 2580, we get 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

Step 14:
4830 divided by 699 is 6 with a remainder of 636.
The number 6 becomes the next digit in our result. 
Result so far: 87839.085836
If we subtract 4194 from 4830, we get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Moving on to step 15:
When dividing 6360 by 699, we get 9 with a remainder of 69.
Record the quotient 9 as the next digit in the result. 
Result so far: 87839.0858369
If we subtract 6291 from 6360, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 16:
699 can be fit into 690 0 times, resulting in a remainder of 690.
Use 0 as the next digit of our solution. 
Result so far: 87839.0858369
Deduct 0 from 690 and we're left with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

The quotient of the division is 87839.0858369, and the remainder is 6.9e-07.
