98636709 ÷ 437 
The aim is to understand the frequency of 437 in 98636709.

Advancing to step 1:
When dividing 9 by 437, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 437

Step 2:
98 divided by 437 is 0 with a remainder of 98.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 98 and we're left with 98.
Fetch the next digit (6) from the dividend, attach it to 98 and continue: 986 / 437

Step 3:
986 divided by 437 is 2 with a remainder of 112.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 874 from 986 to get 112.
Grab the next digit (3) from the dividend, add it to 112, then carry on: 1123 / 437

Going ahead to step 4:
The number 437 fits into 1123 2 times, leaving a remainder of 249.
Put 2 as the next digit of the answer. 
Result so far: 22.0
The remainder is 249 after subtracting 874 from 1123.
Fetch the next digit (6) from the dividend, attach it to 249 and continue: 2496 / 437

Step 5:
437 can be fit into 2496 5 times, resulting in a remainder of 311.
Record the quotient 5 as the next digit in the result. 
Result so far: 225.0
If we take 2185 away from 2496, we end up with 311.
Append the next digit (7) from the dividend to 311 and continue with: 3117 / 437

Moving on to step 6:
437 goes into 3117 7 times with a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 2257.0
Subtracting 3059 from 3117 leaves us with 58.
Take the next digit (0) from the dividend and append it to 58, then repeat: 580 / 437

Step 7:
The number 437 fits into 580 1 times, leaving a remainder of 143.
Put 1 as the next digit of the answer. 
Result so far: 22571.0
Deduct 437 from 580 and we're left with 143.
Bring next digit (9) of the dividend behind the 143 and repeat the process: 1439 / 437

Moving on to step 8:
437 can be fit into 1439 3 times, resulting in a remainder of 128.
Write down 3 as next digit of the result. 
Result so far: 225713.0
Deduct 1311 from 1439 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 9:
1280 divided by 437 is 2 with a remainder of 406.
Write down 2 as next digit of the result. 
Result so far: 225713.2
If we take 874 away from 1280, we end up with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Advancing to step 10:
437 goes into 4060 9 times with a remainder of 127.
Write down 9 as next digit of the result. 
Result so far: 225713.29
If we subtract 3933 from 4060, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Step 11:
437 can be fit into 1270 2 times, resulting in a remainder of 396.
Use 2 as the next digit of our solution. 
Result so far: 225713.292
If we subtract 874 from 1270, we get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Going ahead to step 12:
437 can be fit into 3960 9 times, resulting in a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 225713.2929
If we take 3933 away from 3960, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 13:
437 can be fit into 270 0 times, resulting in a remainder of 270.
The number 0 becomes the next digit in our result. 
Result so far: 225713.2929
Subtract 0 from 270 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 14:
If we divide 2700 by 437, we get 6 and a remainder of 78.
The next digit of our result is 6. 
Result so far: 225713.292906
If we take 2622 away from 2700, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 15:
If we divide 780 by 437, we get 1 and a remainder of 343.
Use 1 as the next digit of our solution. 
Result so far: 225713.2929061
Subtract 437 from 780 to get 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Step 16:
437 can be fit into 3430 7 times, resulting in a remainder of 371.
Use 7 as the next digit of our solution. 
Result so far: 225713.29290617
If we take 3059 away from 3430, we end up with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

After the division, we end up with 225713.29290617 and a remainder of 3.71e-07.
