We're dividing 81836957 by 850 
The aim is to understand the frequency of 850 in 81836957.

Moving on to step 1:
The number 850 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 850

Advancing to step 2:
When dividing 81 by 850, we get 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Include the next digit (8) from the dividend after 81, then repeat: 818 / 850

Step 3:
When dividing 818 by 850, we get 0 with a remainder of 818.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 818 leaves us with 818.
Include the next digit (3) from the dividend after 818, then repeat: 8183 / 850

Advancing to step 4:
The number 850 fits into 8183 9 times, leaving a remainder of 533.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 533 after subtracting 7650 from 8183.
Append the next digit (6) from the dividend to 533 and continue with: 5336 / 850

Advancing to step 5:
If we divide 5336 by 850, we get 6 and a remainder of 236.
The next digit of our result is 6. 
Result so far: 96.0
Deduct 5100 from 5336 and we're left with 236.
Bring next digit (9) of the dividend behind the 236 and repeat the process: 2369 / 850

Moving on to step 6:
If we divide 2369 by 850, we get 2 and a remainder of 669.
Use 2 as the next digit of our solution. 
Result so far: 962.0
The remainder is 669 after subtracting 1700 from 2369.
Grab the next digit (5) from the dividend, add it to 669, then carry on: 6695 / 850

Step 7:
850 can be fit into 6695 7 times, resulting in a remainder of 745.
Put 7 as the next digit of the answer. 
Result so far: 9627.0
Subtract 5950 from 6695 to get 745.
Include the next digit (7) from the dividend after 745, then repeat: 7457 / 850

On to step 8:
When dividing 7457 by 850, we get 8 with a remainder of 657.
Write down 8 as next digit of the result. 
Result so far: 96278.0
The remainder is 657 after subtracting 6800 from 7457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6570, and continue the process.

Advancing to step 9:
850 goes into 6570 7 times with a remainder of 620.
Use 7 as the next digit of our solution. 
Result so far: 96278.7
Subtracting 5950 from 6570 leaves us with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Moving on to step 10:
6200 divided by 850 is 7 with a remainder of 250.
Record the quotient 7 as the next digit in the result. 
Result so far: 96278.77
Subtracting 5950 from 6200 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

The quotient of the division is 96278.77, and the remainder is 0.25.
