18403535 divided by 699 
The aim is to understand the frequency of 699 in 18403535.

Advancing to step 1:
If we divide 1 by 699, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 699

Going ahead to step 2:
699 goes into 18 0 times with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 699

Advancing to step 3:
699 can be fit into 184 0 times, resulting in a remainder of 184.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 184 to get 184.
Grab the next digit (0) from the dividend, add it to 184, then carry on: 1840 / 699

On to step 4:
1840 divided by 699 is 2 with a remainder of 442.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 442 after subtracting 1398 from 1840.
Grab the next digit (3) from the dividend, add it to 442, then carry on: 4423 / 699

Moving on to step 5:
The number 699 fits into 4423 6 times, leaving a remainder of 229.
The next digit of our result is 6. 
Result so far: 26.0
The remainder is 229 after subtracting 4194 from 4423.
Include the next digit (5) from the dividend after 229, then repeat: 2295 / 699

On to step 6:
699 goes into 2295 3 times with a remainder of 198.
Write down 3 as next digit of the result. 
Result so far: 263.0
Deduct 2097 from 2295 and we're left with 198.
Fetch the next digit (3) from the dividend, attach it to 198 and continue: 1983 / 699

Advancing to step 7:
The number 699 fits into 1983 2 times, leaving a remainder of 585.
Put 2 as the next digit of the answer. 
Result so far: 2632.0
The remainder is 585 after subtracting 1398 from 1983.
Bring next digit (5) of the dividend behind the 585 and repeat the process: 5855 / 699

Let's proceed to step 8:
The number 699 fits into 5855 8 times, leaving a remainder of 263.
The number 8 becomes the next digit in our result. 
Result so far: 26328.0
Subtract 5592 from 5855 to get 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Let's proceed to step 9:
699 can be fit into 2630 3 times, resulting in a remainder of 533.
Record the quotient 3 as the next digit in the result. 
Result so far: 26328.3
Deduct 2097 from 2630 and we're left with 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Advancing to step 10:
699 goes into 5330 7 times with a remainder of 437.
The next digit of our result is 7. 
Result so far: 26328.37
If we take 4893 away from 5330, we end up with 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Advancing to step 11:
When dividing 4370 by 699, we get 6 with a remainder of 176.
Use 6 as the next digit of our solution. 
Result so far: 26328.376
Subtracting 4194 from 4370 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 12:
If we divide 1760 by 699, we get 2 and a remainder of 362.
The number 2 becomes the next digit in our result. 
Result so far: 26328.3762
Subtracting 1398 from 1760 leaves us with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Going ahead to step 13:
699 can be fit into 3620 5 times, resulting in a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 26328.37625
If we take 3495 away from 3620, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 14:
The number 699 fits into 1250 1 times, leaving a remainder of 551.
Write down 1 as next digit of the result. 
Result so far: 26328.376251
Subtract 699 from 1250 to get 551.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

Moving on to step 15:
699 can be fit into 5510 7 times, resulting in a remainder of 617.
The next digit of our result is 7. 
Result so far: 26328.3762517
If we take 4893 away from 5510, we end up with 617.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6170, and continue the process.

Let's proceed to step 16:
699 can be fit into 6170 8 times, resulting in a remainder of 578.
Record the quotient 8 as the next digit in the result. 
Result so far: 26328.37625178
Subtract 5592 from 6170 to get 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

The final result is 26328.37625178 with a remainder of 5.78e-07.
