99889386 divided by 699 
The aim is to understand the frequency of 699 in 99889386.

Going ahead to step 1:
When dividing 9 by 699, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 699

Let's proceed to step 2:
699 can be fit into 99 0 times, resulting in a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Grab the next digit (8) from the dividend, add it to 99, then carry on: 998 / 699

Moving on to step 3:
998 divided by 699 is 1 with a remainder of 299.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 699 from 998 leaves us with 299.
Take the next digit (8) from the dividend and append it to 299, then repeat: 2998 / 699

Advancing to step 4:
2998 divided by 699 is 4 with a remainder of 202.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we subtract 2796 from 2998, we get 202.
Take the next digit (9) from the dividend and append it to 202, then repeat: 2029 / 699

On to step 5:
699 goes into 2029 2 times with a remainder of 631.
Use 2 as the next digit of our solution. 
Result so far: 142.0
Deduct 1398 from 2029 and we're left with 631.
Take the next digit (3) from the dividend and append it to 631, then repeat: 6313 / 699

Step 6:
If we divide 6313 by 699, we get 9 and a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 1429.0
If we subtract 6291 from 6313, we get 22.
Take the next digit (8) from the dividend and append it to 22, then repeat: 228 / 699

On to step 7:
The number 699 fits into 228 0 times, leaving a remainder of 228.
Write down 0 as next digit of the result. 
Result so far: 14290.0
Deduct 0 from 228 and we're left with 228.
Include the next digit (6) from the dividend after 228, then repeat: 2286 / 699

Step 8:
When dividing 2286 by 699, we get 3 with a remainder of 189.
Write down 3 as next digit of the result. 
Result so far: 142903.0
Deduct 2097 from 2286 and we're left with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Going ahead to step 9:
699 goes into 1890 2 times with a remainder of 492.
Use 2 as the next digit of our solution. 
Result so far: 142903.2
Subtracting 1398 from 1890 leaves us with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

On to step 10:
The number 699 fits into 4920 7 times, leaving a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 142903.27
The remainder is 27 after subtracting 4893 from 4920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 11:
The number 699 fits into 270 0 times, leaving a remainder of 270.
Write down 0 as next digit of the result. 
Result so far: 142903.27
Deduct 0 from 270 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 12:
If we divide 2700 by 699, we get 3 and a remainder of 603.
The number 3 becomes the next digit in our result. 
Result so far: 142903.2703
Deduct 2097 from 2700 and we're left with 603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6030, and continue the process.

Let's proceed to step 13:
699 goes into 6030 8 times with a remainder of 438.
Use 8 as the next digit of our solution. 
Result so far: 142903.27038
If we subtract 5592 from 6030, we get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Advancing to step 14:
4380 divided by 699 is 6 with a remainder of 186.
The number 6 becomes the next digit in our result. 
Result so far: 142903.270386
Subtracting 4194 from 4380 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 15:
1860 divided by 699 is 2 with a remainder of 462.
Use 2 as the next digit of our solution. 
Result so far: 142903.2703862
Subtract 1398 from 1860 to get 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Moving on to step 16:
If we divide 4620 by 699, we get 6 and a remainder of 426.
Record the quotient 6 as the next digit in the result. 
Result so far: 142903.27038626
The remainder is 426 after subtracting 4194 from 4620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

The final result is 142903.27038626 with a remainder of 4.26e-07.
