73503711 ÷ 938 
The aim is to understand the frequency of 938 in 73503711.

On to step 1:
938 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 938

Step 2:
73 divided by 938 is 0 with a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Include the next digit (5) from the dividend after 73, then repeat: 735 / 938

Moving on to step 3:
If we divide 735 by 938, we get 0 and a remainder of 735.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 735, we end up with 735.
Fetch the next digit (0) from the dividend, attach it to 735 and continue: 7350 / 938

Going ahead to step 4:
If we divide 7350 by 938, we get 7 and a remainder of 784.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 6566 from 7350, we get 784.
Fetch the next digit (3) from the dividend, attach it to 784 and continue: 7843 / 938

On to step 5:
938 goes into 7843 8 times with a remainder of 339.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Subtracting 7504 from 7843 leaves us with 339.
Append the next digit (7) from the dividend to 339 and continue with: 3397 / 938

Step 6:
If we divide 3397 by 938, we get 3 and a remainder of 583.
Record the quotient 3 as the next digit in the result. 
Result so far: 783.0
If we take 2814 away from 3397, we end up with 583.
Grab the next digit (1) from the dividend, add it to 583, then carry on: 5831 / 938

Step 7:
If we divide 5831 by 938, we get 6 and a remainder of 203.
The next digit of our result is 6. 
Result so far: 7836.0
The remainder is 203 after subtracting 5628 from 5831.
Include the next digit (1) from the dividend after 203, then repeat: 2031 / 938

Advancing to step 8:
2031 divided by 938 is 2 with a remainder of 155.
The next digit of our result is 2. 
Result so far: 78362.0
Subtract 1876 from 2031 to get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Moving on to step 9:
1550 divided by 938 is 1 with a remainder of 612.
Use 1 as the next digit of our solution. 
Result so far: 78362.1
If we subtract 938 from 1550, we get 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Step 10:
938 goes into 6120 6 times with a remainder of 492.
The next digit of our result is 6. 
Result so far: 78362.16
Subtracting 5628 from 6120 leaves us with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

On to step 11:
938 can be fit into 4920 5 times, resulting in a remainder of 230.
Put 5 as the next digit of the answer. 
Result so far: 78362.165
The remainder is 230 after subtracting 4690 from 4920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 12:
When dividing 2300 by 938, we get 2 with a remainder of 424.
The next digit of our result is 2. 
Result so far: 78362.1652
Subtracting 1876 from 2300 leaves us with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

On to step 13:
4240 divided by 938 is 4 with a remainder of 488.
Write down 4 as next digit of the result. 
Result so far: 78362.16524
The remainder is 488 after subtracting 3752 from 4240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Advancing to step 14:
If we divide 4880 by 938, we get 5 and a remainder of 190.
Put 5 as the next digit of the answer. 
Result so far: 78362.165245
Subtracting 4690 from 4880 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 15:
The number 938 fits into 1900 2 times, leaving a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 78362.1652452
Subtract 1876 from 1900 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.

On to step 16:
The number 938 fits into 240 0 times, leaving a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 78362.1652452
Deduct 0 from 240 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final result is 78362.1652452 with a remainder of 2.4e-07.
