We're dividing 37311997 by 437 
The aim is to understand the frequency of 437 in 37311997.

Let's proceed to step 1:
437 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 437

Let's proceed to step 2:
When dividing 37 by 437, we get 0 with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Grab the next digit (3) from the dividend, add it to 37, then carry on: 373 / 437

Advancing to step 3:
When dividing 373 by 437, we get 0 with a remainder of 373.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 373 and we're left with 373.
Include the next digit (1) from the dividend after 373, then repeat: 3731 / 437

Moving on to step 4:
3731 divided by 437 is 8 with a remainder of 235.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 3496 from 3731 and we're left with 235.
Fetch the next digit (1) from the dividend, attach it to 235 and continue: 2351 / 437

Let's proceed to step 5:
437 can be fit into 2351 5 times, resulting in a remainder of 166.
Write down 5 as next digit of the result. 
Result so far: 85.0
Subtract 2185 from 2351 to get 166.
Bring next digit (9) of the dividend behind the 166 and repeat the process: 1669 / 437

Step 6:
437 goes into 1669 3 times with a remainder of 358.
Write down 3 as next digit of the result. 
Result so far: 853.0
Subtract 1311 from 1669 to get 358.
Append the next digit (9) from the dividend to 358 and continue with: 3589 / 437

On to step 7:
3589 divided by 437 is 8 with a remainder of 93.
The number 8 becomes the next digit in our result. 
Result so far: 8538.0
Deduct 3496 from 3589 and we're left with 93.
Grab the next digit (7) from the dividend, add it to 93, then carry on: 937 / 437

Advancing to step 8:
If we divide 937 by 437, we get 2 and a remainder of 63.
Write down 2 as next digit of the result. 
Result so far: 85382.0
The remainder is 63 after subtracting 874 from 937.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 9:
437 goes into 630 1 times with a remainder of 193.
Use 1 as the next digit of our solution. 
Result so far: 85382.1
Deduct 437 from 630 and we're left with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

On to step 10:
The number 437 fits into 1930 4 times, leaving a remainder of 182.
Record the quotient 4 as the next digit in the result. 
Result so far: 85382.14
Subtract 1748 from 1930 to get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Step 11:
If we divide 1820 by 437, we get 4 and a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 85382.144
Subtract 1748 from 1820 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 85382.144 with a remaining 0.0072.
