68236764 ÷ 850 
The aim is to understand the frequency of 850 in 68236764.

Going ahead to step 1:
6 divided by 850 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 850

Step 2:
If we divide 68 by 850, we get 0 and a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Include the next digit (2) from the dividend after 68, then repeat: 682 / 850

Step 3:
850 can be fit into 682 0 times, resulting in a remainder of 682.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 682, we get 682.
Fetch the next digit (3) from the dividend, attach it to 682 and continue: 6823 / 850

Advancing to step 4:
If we divide 6823 by 850, we get 8 and a remainder of 23.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 6800 from 6823 leaves us with 23.
Grab the next digit (6) from the dividend, add it to 23, then carry on: 236 / 850

Moving on to step 5:
236 divided by 850 is 0 with a remainder of 236.
Use 0 as the next digit of our solution. 
Result so far: 80.0
If we take 0 away from 236, we end up with 236.
Append the next digit (7) from the dividend to 236 and continue with: 2367 / 850

Advancing to step 6:
If we divide 2367 by 850, we get 2 and a remainder of 667.
Write down 2 as next digit of the result. 
Result so far: 802.0
Subtract 1700 from 2367 to get 667.
Take the next digit (6) from the dividend and append it to 667, then repeat: 6676 / 850

Step 7:
850 can be fit into 6676 7 times, resulting in a remainder of 726.
Write down 7 as next digit of the result. 
Result so far: 8027.0
If we take 5950 away from 6676, we end up with 726.
Fetch the next digit (4) from the dividend, attach it to 726 and continue: 7264 / 850

Step 8:
If we divide 7264 by 850, we get 8 and a remainder of 464.
Record the quotient 8 as the next digit in the result. 
Result so far: 80278.0
The remainder is 464 after subtracting 6800 from 7264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

On to step 9:
4640 divided by 850 is 5 with a remainder of 390.
The next digit of our result is 5. 
Result so far: 80278.5
Deduct 4250 from 4640 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Advancing to step 10:
850 goes into 3900 4 times with a remainder of 500.
Write down 4 as next digit of the result. 
Result so far: 80278.54
If we take 3400 away from 3900, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 11:
850 can be fit into 5000 5 times, resulting in a remainder of 750.
Record the quotient 5 as the next digit in the result. 
Result so far: 80278.545
Deduct 4250 from 5000 and we're left with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

On to step 12:
When dividing 7500 by 850, we get 8 with a remainder of 700.
Record the quotient 8 as the next digit in the result. 
Result so far: 80278.5458
If we take 6800 away from 7500, 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.

Moving on to step 13:
7000 divided by 850 is 8 with a remainder of 200.
Write down 8 as next digit of the result. 
Result so far: 80278.54588
If we subtract 6800 from 7000, we 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.

The final result is 80278.54588 with a remainder of 0.0002.
