We divide 91455051 by 850
The aim is to understand the frequency of 850 in 91455051.

Step 1:
9 divided by 850 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 850

Moving on to step 2:
The number 850 fits into 91 0 times, leaving a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 91 leaves us with 91.
Take the next digit (4) from the dividend and append it to 91, then repeat: 914 / 850

Step 3:
914 divided by 850 is 1 with a remainder of 64.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 850 from 914 and we're left with 64.
Take the next digit (5) from the dividend and append it to 64, then repeat: 645 / 850

Advancing to step 4:
850 goes into 645 0 times with a remainder of 645.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 645, we end up with 645.
Include the next digit (5) from the dividend after 645, then repeat: 6455 / 850

Going ahead to step 5:
When dividing 6455 by 850, we get 7 with a remainder of 505.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
If we take 5950 away from 6455, we end up with 505.
Grab the next digit (0) from the dividend, add it to 505, then carry on: 5050 / 850

Going ahead to step 6:
When dividing 5050 by 850, we get 5 with a remainder of 800.
The number 5 becomes the next digit in our result. 
Result so far: 1075.0
If we take 4250 away from 5050, we end up with 800.
Bring next digit (5) of the dividend behind the 800 and repeat the process: 8005 / 850

Let's proceed to step 7:
850 can be fit into 8005 9 times, resulting in a remainder of 355.
Use 9 as the next digit of our solution. 
Result so far: 10759.0
The remainder is 355 after subtracting 7650 from 8005.
Fetch the next digit (1) from the dividend, attach it to 355 and continue: 3551 / 850

On to step 8:
850 can be fit into 3551 4 times, resulting in a remainder of 151.
Use 4 as the next digit of our solution. 
Result so far: 107594.0
Subtract 3400 from 3551 to get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Step 9:
When dividing 1510 by 850, we get 1 with a remainder of 660.
Put 1 as the next digit of the answer. 
Result so far: 107594.1
If we subtract 850 from 1510, we get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Step 10:
When dividing 6600 by 850, we get 7 with a remainder of 650.
Record the quotient 7 as the next digit in the result. 
Result so far: 107594.17
Subtracting 5950 from 6600 leaves us with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

On to step 11:
850 can be fit into 6500 7 times, resulting in a remainder of 550.
Put 7 as the next digit of the answer. 
Result so far: 107594.177
Subtracting 5950 from 6500 leaves us with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

After the division, we end up with 107594.177 and a remainder of 0.055.
