43988187 divided by 434 
The aim is to understand the frequency of 434 in 43988187.

Step 1:
434 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 434

On to step 2:
When dividing 43 by 434, we get 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Append the next digit (9) from the dividend to 43 and continue with: 439 / 434

Step 3:
If we divide 439 by 434, we get 1 and a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 434 away from 439, we end up with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 434

Going ahead to step 4:
434 goes into 58 0 times with a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 58 after subtracting 0 from 58.
Grab the next digit (8) from the dividend, add it to 58, then carry on: 588 / 434

Going ahead to step 5:
The number 434 fits into 588 1 times, leaving a remainder of 154.
Write down 1 as next digit of the result. 
Result so far: 101.0
If we subtract 434 from 588, we get 154.
Bring next digit (1) of the dividend behind the 154 and repeat the process: 1541 / 434

Moving on to step 6:
The number 434 fits into 1541 3 times, leaving a remainder of 239.
The next digit of our result is 3. 
Result so far: 1013.0
The remainder is 239 after subtracting 1302 from 1541.
Fetch the next digit (8) from the dividend, attach it to 239 and continue: 2398 / 434

On to step 7:
434 can be fit into 2398 5 times, resulting in a remainder of 228.
Use 5 as the next digit of our solution. 
Result so far: 10135.0
Deduct 2170 from 2398 and we're left with 228.
Append the next digit (7) from the dividend to 228 and continue with: 2287 / 434

Let's proceed to step 8:
434 goes into 2287 5 times with a remainder of 117.
Put 5 as the next digit of the answer. 
Result so far: 101355.0
Subtract 2170 from 2287 to get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Step 9:
The number 434 fits into 1170 2 times, leaving a remainder of 302.
Use 2 as the next digit of our solution. 
Result so far: 101355.2
If we take 868 away from 1170, we end up with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Let's proceed to step 10:
434 goes into 3020 6 times with a remainder of 416.
Put 6 as the next digit of the answer. 
Result so far: 101355.26
Subtracting 2604 from 3020 leaves us with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 11:
When dividing 4160 by 434, we get 9 with a remainder of 254.
Put 9 as the next digit of the answer. 
Result so far: 101355.269
Deduct 3906 from 4160 and we're left with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Advancing to step 12:
The number 434 fits into 2540 5 times, leaving a remainder of 370.
Record the quotient 5 as the next digit in the result. 
Result so far: 101355.2695
If we subtract 2170 from 2540, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 13:
When dividing 3700 by 434, we get 8 with a remainder of 228.
Use 8 as the next digit of our solution. 
Result so far: 101355.26958
The remainder is 228 after subtracting 3472 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Moving on to step 14:
434 goes into 2280 5 times with a remainder of 110.
The number 5 becomes the next digit in our result. 
Result so far: 101355.269585
The remainder is 110 after subtracting 2170 from 2280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 15:
434 goes into 1100 2 times with a remainder of 232.
The next digit of our result is 2. 
Result so far: 101355.2695852
The remainder is 232 after subtracting 868 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 16:
When dividing 2320 by 434, we get 5 with a remainder of 150.
Write down 5 as next digit of the result. 
Result so far: 101355.26958525
Subtract 2170 from 2320 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

In conclusion, the division gives 101355.26958525 with a balance of 1.5e-07.
