99372158 ÷ 436 
The aim is to understand the frequency of 436 in 99372158.

On to step 1:
If we divide 9 by 436, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 436

On to step 2:
When dividing 99 by 436, we get 0 with a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Grab the next digit (3) from the dividend, add it to 99, then carry on: 993 / 436

Step 3:
436 can be fit into 993 2 times, resulting in a remainder of 121.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 872 away from 993, we end up with 121.
Fetch the next digit (7) from the dividend, attach it to 121 and continue: 1217 / 436

Advancing to step 4:
When dividing 1217 by 436, we get 2 with a remainder of 345.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
If we subtract 872 from 1217, we get 345.
Fetch the next digit (2) from the dividend, attach it to 345 and continue: 3452 / 436

Going ahead to step 5:
The number 436 fits into 3452 7 times, leaving a remainder of 400.
Record the quotient 7 as the next digit in the result. 
Result so far: 227.0
The remainder is 400 after subtracting 3052 from 3452.
Grab the next digit (1) from the dividend, add it to 400, then carry on: 4001 / 436

Moving on to step 6:
If we divide 4001 by 436, we get 9 and a remainder of 77.
The next digit of our result is 9. 
Result so far: 2279.0
If we take 3924 away from 4001, we end up with 77.
Fetch the next digit (5) from the dividend, attach it to 77 and continue: 775 / 436

Going ahead to step 7:
The number 436 fits into 775 1 times, leaving a remainder of 339.
Put 1 as the next digit of the answer. 
Result so far: 22791.0
Deduct 436 from 775 and we're left with 339.
Append the next digit (8) from the dividend to 339 and continue with: 3398 / 436

Moving on to step 8:
3398 divided by 436 is 7 with a remainder of 346.
Record the quotient 7 as the next digit in the result. 
Result so far: 227917.0
If we take 3052 away from 3398, we end up with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Advancing to step 9:
3460 divided by 436 is 7 with a remainder of 408.
Put 7 as the next digit of the answer. 
Result so far: 227917.7
Subtracting 3052 from 3460 leaves us with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

On to step 10:
If we divide 4080 by 436, we get 9 and a remainder of 156.
Record the quotient 9 as the next digit in the result. 
Result so far: 227917.79
If we take 3924 away from 4080, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 11:
When dividing 1560 by 436, we get 3 with a remainder of 252.
Record the quotient 3 as the next digit in the result. 
Result so far: 227917.793
Subtracting 1308 from 1560 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Advancing to step 12:
436 goes into 2520 5 times with a remainder of 340.
Write down 5 as next digit of the result. 
Result so far: 227917.7935
Subtracting 2180 from 2520 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 13:
436 goes into 3400 7 times with a remainder of 348.
Use 7 as the next digit of our solution. 
Result so far: 227917.79357
Subtract 3052 from 3400 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 14:
3480 divided by 436 is 7 with a remainder of 428.
Record the quotient 7 as the next digit in the result. 
Result so far: 227917.793577
If we take 3052 away from 3480, we end up with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

The final outcome is 227917.793577, with a leftover of 4.28e-05.
