We look at the division of 721421 by 92 
The aim is to understand the frequency of 92 in 721421.

Moving on to step 1:
If we divide 7 by 92, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 92

Let's proceed to step 2:
When dividing 72 by 92, we get 0 with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Bring next digit (1) of the dividend behind the 72 and repeat the process: 721 / 92

Step 3:
When dividing 721 by 92, we get 7 with a remainder of 77.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 644 from 721 leaves us with 77.
Grab the next digit (4) from the dividend, add it to 77, then carry on: 774 / 92

Going ahead to step 4:
If we divide 774 by 92, we get 8 and a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
If we subtract 736 from 774, we get 38.
Fetch the next digit (2) from the dividend, attach it to 38 and continue: 382 / 92

Step 5:
When dividing 382 by 92, we get 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 784.0
Subtract 368 from 382 to get 14.
Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 92

Let's proceed to step 6:
141 divided by 92 is 1 with a remainder of 49.
The next digit of our result is 1. 
Result so far: 7841.0
Subtract 92 from 141 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 7:
If we divide 490 by 92, we get 5 and a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 7841.5
Deduct 460 from 490 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
300 divided by 92 is 3 with a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 7841.53
If we take 276 away from 300, we end up with 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 9:
92 goes into 240 2 times with a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 7841.532
Subtracting 184 from 240 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 10:
If we divide 560 by 92, we get 6 and a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 7841.5326
The remainder is 8 after subtracting 552 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
92 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 7841.5326
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 12:
92 can be fit into 800 8 times, resulting in a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 7841.532608
The remainder is 64 after subtracting 736 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 13:
640 divided by 92 is 6 with a remainder of 88.
Write down 6 as next digit of the result. 
Result so far: 7841.5326086
Subtract 552 from 640 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 14:
92 can be fit into 880 9 times, resulting in a remainder of 52.
Use 9 as the next digit of our solution. 
Result so far: 7841.53260869
Deduct 828 from 880 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The quotient of the division is 7841.53260869, and the remainder is 5.2e-08.
