We look at the division of 85381680 by 934 
The aim is to understand the frequency of 934 in 85381680.

On to step 1:
When dividing 8 by 934, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 934

On to step 2:
934 goes into 85 0 times with a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Fetch the next digit (3) from the dividend, attach it to 85 and continue: 853 / 934

Moving on to step 3:
934 goes into 853 0 times with a remainder of 853.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 853 after subtracting 0 from 853.
Include the next digit (8) from the dividend after 853, then repeat: 8538 / 934

Advancing to step 4:
934 goes into 8538 9 times with a remainder of 132.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 8406 from 8538 and we're left with 132.
Append the next digit (1) from the dividend to 132 and continue with: 1321 / 934

On to step 5:
If we divide 1321 by 934, we get 1 and a remainder of 387.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
If we subtract 934 from 1321, we get 387.
Bring next digit (6) of the dividend behind the 387 and repeat the process: 3876 / 934

On to step 6:
3876 divided by 934 is 4 with a remainder of 140.
Put 4 as the next digit of the answer. 
Result so far: 914.0
If we subtract 3736 from 3876, we get 140.
Bring next digit (8) of the dividend behind the 140 and repeat the process: 1408 / 934

Moving on to step 7:
The number 934 fits into 1408 1 times, leaving a remainder of 474.
Write down 1 as next digit of the result. 
Result so far: 9141.0
The remainder is 474 after subtracting 934 from 1408.
Grab the next digit (0) from the dividend, add it to 474, then carry on: 4740 / 934

Advancing to step 8:
934 can be fit into 4740 5 times, resulting in a remainder of 70.
The next digit of our result is 5. 
Result so far: 91415.0
Subtract 4670 from 4740 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 9:
When dividing 700 by 934, we get 0 with a remainder of 700.
The next digit of our result is 0. 
Result so far: 91415.0
Deduct 0 from 700 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Moving on to step 10:
934 can be fit into 7000 7 times, resulting in a remainder of 462.
Record the quotient 7 as the next digit in the result. 
Result so far: 91415.07
If we subtract 6538 from 7000, we get 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

On to step 11:
When dividing 4620 by 934, we get 4 with a remainder of 884.
Use 4 as the next digit of our solution. 
Result so far: 91415.074
Subtracting 3736 from 4620 leaves us with 884.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8840, and continue the process.

Moving on to step 12:
If we divide 8840 by 934, we get 9 and a remainder of 434.
Use 9 as the next digit of our solution. 
Result so far: 91415.0749
If we subtract 8406 from 8840, we get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Moving on to step 13:
934 goes into 4340 4 times with a remainder of 604.
Record the quotient 4 as the next digit in the result. 
Result so far: 91415.07494
Deduct 3736 from 4340 and we're left with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Step 14:
When dividing 6040 by 934, we get 6 with a remainder of 436.
The number 6 becomes the next digit in our result. 
Result so far: 91415.074946
Subtracting 5604 from 6040 leaves us with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

On to step 15:
The number 934 fits into 4360 4 times, leaving a remainder of 624.
Put 4 as the next digit of the answer. 
Result so far: 91415.0749464
If we take 3736 away from 4360, we end up with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Let's proceed to step 16:
6240 divided by 934 is 6 with a remainder of 636.
Write down 6 as next digit of the result. 
Result so far: 91415.07494646
If we take 5604 away from 6240, we end up with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

After the division, we end up with 91415.07494646 and a remainder of 6.36e-07.
