We're dividing 80457186 by 938 
The aim is to understand the frequency of 938 in 80457186.

Going ahead to step 1:
The number 938 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 938

Step 2:
When dividing 80 by 938, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Fetch the next digit (4) from the dividend, attach it to 80 and continue: 804 / 938

Advancing to step 3:
The number 938 fits into 804 0 times, leaving a remainder of 804.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 804 leaves us with 804.
Grab the next digit (5) from the dividend, add it to 804, then carry on: 8045 / 938

On to step 4:
When dividing 8045 by 938, we get 8 with a remainder of 541.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 7504 from 8045 leaves us with 541.
Fetch the next digit (7) from the dividend, attach it to 541 and continue: 5417 / 938

Going ahead to step 5:
If we divide 5417 by 938, we get 5 and a remainder of 727.
The next digit of our result is 5. 
Result so far: 85.0
If we take 4690 away from 5417, we end up with 727.
Include the next digit (1) from the dividend after 727, then repeat: 7271 / 938

On to step 6:
When dividing 7271 by 938, we get 7 with a remainder of 705.
The number 7 becomes the next digit in our result. 
Result so far: 857.0
Deduct 6566 from 7271 and we're left with 705.
Include the next digit (8) from the dividend after 705, then repeat: 7058 / 938

Advancing to step 7:
The number 938 fits into 7058 7 times, leaving a remainder of 492.
The number 7 becomes the next digit in our result. 
Result so far: 8577.0
Subtracting 6566 from 7058 leaves us with 492.
Bring next digit (6) of the dividend behind the 492 and repeat the process: 4926 / 938

Going ahead to step 8:
The number 938 fits into 4926 5 times, leaving a remainder of 236.
Write down 5 as next digit of the result. 
Result so far: 85775.0
Deduct 4690 from 4926 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Let's proceed to step 9:
If we divide 2360 by 938, we get 2 and a remainder of 484.
Write down 2 as next digit of the result. 
Result so far: 85775.2
The remainder is 484 after subtracting 1876 from 2360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Moving on to step 10:
If we divide 4840 by 938, we get 5 and a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 85775.25
If we subtract 4690 from 4840, we 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.

On to step 11:
938 can be fit into 1500 1 times, resulting in a remainder of 562.
Put 1 as the next digit of the answer. 
Result so far: 85775.251
Subtract 938 from 1500 to get 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Advancing to step 12:
When dividing 5620 by 938, we get 5 with a remainder of 930.
Record the quotient 5 as the next digit in the result. 
Result so far: 85775.2515
The remainder is 930 after subtracting 4690 from 5620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9300, and continue the process.

Let's proceed to step 13:
If we divide 9300 by 938, we get 9 and a remainder of 858.
Record the quotient 9 as the next digit in the result. 
Result so far: 85775.25159
The remainder is 858 after subtracting 8442 from 9300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8580, and continue the process.

Advancing to step 14:
938 can be fit into 8580 9 times, resulting in a remainder of 138.
Record the quotient 9 as the next digit in the result. 
Result so far: 85775.251599
Subtracting 8442 from 8580 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

After the division, we end up with 85775.251599 and a remainder of 1.38e-05.
