11616209 ÷ 850 
The aim is to understand the frequency of 850 in 11616209.

Moving on to step 1:
1 divided by 850 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 850

Step 2:
When dividing 11 by 850, we get 0 with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 850

Step 3:
If we divide 116 by 850, we get 0 and a remainder of 116.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 116, we get 116.
Grab the next digit (1) from the dividend, add it to 116, then carry on: 1161 / 850

Advancing to step 4:
850 can be fit into 1161 1 times, resulting in a remainder of 311.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 850 from 1161 leaves us with 311.
Take the next digit (6) from the dividend and append it to 311, then repeat: 3116 / 850

On to step 5:
The number 850 fits into 3116 3 times, leaving a remainder of 566.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 2550 from 3116 and we're left with 566.
Fetch the next digit (2) from the dividend, attach it to 566 and continue: 5662 / 850

Let's proceed to step 6:
850 goes into 5662 6 times with a remainder of 562.
Write down 6 as next digit of the result. 
Result so far: 136.0
If we subtract 5100 from 5662, we get 562.
Fetch the next digit (0) from the dividend, attach it to 562 and continue: 5620 / 850

Going ahead to step 7:
When dividing 5620 by 850, we get 6 with a remainder of 520.
Write down 6 as next digit of the result. 
Result so far: 1366.0
If we take 5100 away from 5620, we end up with 520.
Include the next digit (9) from the dividend after 520, then repeat: 5209 / 850

Step 8:
850 can be fit into 5209 6 times, resulting in a remainder of 109.
Record the quotient 6 as the next digit in the result. 
Result so far: 13666.0
The remainder is 109 after subtracting 5100 from 5209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Going ahead to step 9:
850 goes into 1090 1 times with a remainder of 240.
Put 1 as the next digit of the answer. 
Result so far: 13666.1
If we take 850 away from 1090, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 10:
850 goes into 2400 2 times with a remainder of 700.
The next digit of our result is 2. 
Result so far: 13666.12
If we take 1700 away from 2400, we end up with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Step 11:
The number 850 fits into 7000 8 times, leaving a remainder of 200.
Use 8 as the next digit of our solution. 
Result so far: 13666.128
Subtract 6800 from 7000 to get 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 12:
850 goes into 2000 2 times with a remainder of 300.
Record the quotient 2 as the next digit in the result. 
Result so far: 13666.1282
Subtract 1700 from 2000 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 13:
If we divide 3000 by 850, we get 3 and a remainder of 450.
The next digit of our result is 3. 
Result so far: 13666.12823
Subtracting 2550 from 3000 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 14:
850 can be fit into 4500 5 times, resulting in a remainder of 250.
Record the quotient 5 as the next digit in the result. 
Result so far: 13666.128235
Subtract 4250 from 4500 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 15:
If we divide 2500 by 850, we get 2 and a remainder of 800.
Put 2 as the next digit of the answer. 
Result so far: 13666.1282352
The remainder is 800 after subtracting 1700 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Step 16:
8000 divided by 850 is 9 with a remainder of 350.
Record the quotient 9 as the next digit in the result. 
Result so far: 13666.12823529
The remainder is 350 after subtracting 7650 from 8000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

The final outcome is 13666.12823529, with a leftover of 3.5e-07.
