We're dividing 83961702 by 450 
The aim is to understand the frequency of 450 in 83961702.

Advancing to step 1:
8 divided by 450 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 450

Step 2:
450 can be fit into 83 0 times, resulting in a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Append the next digit (9) from the dividend to 83 and continue with: 839 / 450

Step 3:
450 can be fit into 839 1 times, resulting in a remainder of 389.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 450 from 839 to get 389.
Grab the next digit (6) from the dividend, add it to 389, then carry on: 3896 / 450

Advancing to step 4:
The number 450 fits into 3896 8 times, leaving a remainder of 296.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we take 3600 away from 3896, we end up with 296.
Fetch the next digit (1) from the dividend, attach it to 296 and continue: 2961 / 450

Going ahead to step 5:
450 goes into 2961 6 times with a remainder of 261.
The number 6 becomes the next digit in our result. 
Result so far: 186.0
Subtract 2700 from 2961 to get 261.
Include the next digit (7) from the dividend after 261, then repeat: 2617 / 450

Advancing to step 6:
450 goes into 2617 5 times with a remainder of 367.
Record the quotient 5 as the next digit in the result. 
Result so far: 1865.0
Deduct 2250 from 2617 and we're left with 367.
Grab the next digit (0) from the dividend, add it to 367, then carry on: 3670 / 450

Step 7:
When dividing 3670 by 450, we get 8 with a remainder of 70.
The next digit of our result is 8. 
Result so far: 18658.0
Subtract 3600 from 3670 to get 70.
Fetch the next digit (2) from the dividend, attach it to 70 and continue: 702 / 450

On to step 8:
When dividing 702 by 450, we get 1 with a remainder of 252.
The number 1 becomes the next digit in our result. 
Result so far: 186581.0
If we subtract 450 from 702, we get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 9:
If we divide 2520 by 450, we get 5 and a remainder of 270.
Write down 5 as next digit of the result. 
Result so far: 186581.5
If we take 2250 away from 2520, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 10:
If we divide 2700 by 450, we get 6 and a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 186581.56
Deduct 2700 from 2700 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
If we divide 0 by 450, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 186581.56
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 12:
The number 450 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 186581.56
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 186581.56, with a leftover of 0.0.
