We look at the division of 851010 by 93 
The aim is to understand the frequency of 93 in 851010.

On to step 1:
8 divided by 93 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 93

Moving on to step 2:
93 can be fit into 85 0 times, resulting in a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Grab the next digit (1) from the dividend, add it to 85, then carry on: 851 / 93

Moving on to step 3:
If we divide 851 by 93, we get 9 and a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 837 from 851, we get 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 93

Moving on to step 4:
The number 93 fits into 140 1 times, leaving a remainder of 47.
Put 1 as the next digit of the answer. 
Result so far: 91.0
If we take 93 away from 140, we end up with 47.
Include the next digit (1) from the dividend after 47, then repeat: 471 / 93

On to step 5:
When dividing 471 by 93, we get 5 with a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 915.0
If we subtract 465 from 471, we get 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 93

Advancing to step 6:
The number 93 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 9150.0
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 7:
600 divided by 93 is 6 with a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 9150.6
Subtract 558 from 600 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 8:
420 divided by 93 is 4 with a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 9150.64
If we take 372 away from 420, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
If we divide 480 by 93, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 9150.645
If we take 465 away from 480, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
The number 93 fits into 150 1 times, leaving a remainder of 57.
Put 1 as the next digit of the answer. 
Result so far: 9150.6451
Subtract 93 from 150 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 11:
If we divide 570 by 93, we get 6 and a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 9150.64516
If we take 558 away from 570, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
120 divided by 93 is 1 with a remainder of 27.
The next digit of our result is 1. 
Result so far: 9150.645161
If we take 93 away from 120, 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.

Advancing to step 13:
93 can be fit into 270 2 times, resulting in a remainder of 84.
Write down 2 as next digit of the result. 
Result so far: 9150.6451612
The remainder is 84 after subtracting 186 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 14:
840 divided by 93 is 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 9150.64516129
If we subtract 837 from 840, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 9150.64516129 and a remainder of 3e-09.
