Let's divide 83937435 by 438
The aim is to understand the frequency of 438 in 83937435.

Advancing to step 1:
438 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 438

Advancing to step 2:
When dividing 83 by 438, we get 0 with a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Bring next digit (9) of the dividend behind the 83 and repeat the process: 839 / 438

Going ahead to step 3:
438 can be fit into 839 1 times, resulting in a remainder of 401.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 438 from 839, we get 401.
Fetch the next digit (3) from the dividend, attach it to 401 and continue: 4013 / 438

Step 4:
The number 438 fits into 4013 9 times, leaving a remainder of 71.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Deduct 3942 from 4013 and we're left with 71.
Append the next digit (7) from the dividend to 71 and continue with: 717 / 438

Step 5:
717 divided by 438 is 1 with a remainder of 279.
Put 1 as the next digit of the answer. 
Result so far: 191.0
If we subtract 438 from 717, we get 279.
Append the next digit (4) from the dividend to 279 and continue with: 2794 / 438

On to step 6:
438 can be fit into 2794 6 times, resulting in a remainder of 166.
The next digit of our result is 6. 
Result so far: 1916.0
Subtracting 2628 from 2794 leaves us with 166.
Append the next digit (3) from the dividend to 166 and continue with: 1663 / 438

Let's proceed to step 7:
If we divide 1663 by 438, we get 3 and a remainder of 349.
Write down 3 as next digit of the result. 
Result so far: 19163.0
Deduct 1314 from 1663 and we're left with 349.
Grab the next digit (5) from the dividend, add it to 349, then carry on: 3495 / 438

Step 8:
If we divide 3495 by 438, we get 7 and a remainder of 429.
The number 7 becomes the next digit in our result. 
Result so far: 191637.0
Subtract 3066 from 3495 to get 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Step 9:
The number 438 fits into 4290 9 times, leaving a remainder of 348.
The number 9 becomes the next digit in our result. 
Result so far: 191637.9
Subtract 3942 from 4290 to get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Advancing to step 10:
When dividing 3480 by 438, we get 7 with a remainder of 414.
The next digit of our result is 7. 
Result so far: 191637.97
If we take 3066 away from 3480, we end up with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Going ahead to step 11:
When dividing 4140 by 438, we get 9 with a remainder of 198.
The number 9 becomes the next digit in our result. 
Result so far: 191637.979
If we subtract 3942 from 4140, we get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Step 12:
438 can be fit into 1980 4 times, resulting in a remainder of 228.
The next digit of our result is 4. 
Result so far: 191637.9794
Deduct 1752 from 1980 and we're left with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Going ahead to step 13:
438 can be fit into 2280 5 times, resulting in a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 191637.97945
Subtracting 2190 from 2280 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 14:
900 divided by 438 is 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 191637.979452
Subtract 876 from 900 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 15:
240 divided by 438 is 0 with a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 191637.979452
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 16:
The number 438 fits into 2400 5 times, leaving a remainder of 210.
Put 5 as the next digit of the answer. 
Result so far: 191637.97945205
Deduct 2190 from 2400 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

In conclusion, the division gives 191637.97945205 with a balance of 2.1e-07.
