81055988 ÷ 425 
The aim is to understand the frequency of 425 in 81055988.

Let's proceed to step 1:
425 can be fit into 8 0 times, resulting in 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.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 425

On to step 2:
425 can be fit into 81 0 times, resulting in a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Append the next digit (0) from the dividend to 81 and continue with: 810 / 425

Step 3:
If we divide 810 by 425, we get 1 and a remainder of 385.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 425 away from 810, we end up with 385.
Include the next digit (5) from the dividend after 385, then repeat: 3855 / 425

Let's proceed to step 4:
425 can be fit into 3855 9 times, resulting in a remainder of 30.
The next digit of our result is 9. 
Result so far: 19.0
Subtract 3825 from 3855 to get 30.
Fetch the next digit (5) from the dividend, attach it to 30 and continue: 305 / 425

Going ahead to step 5:
If we divide 305 by 425, we get 0 and a remainder of 305.
Write down 0 as next digit of the result. 
Result so far: 190.0
Subtract 0 from 305 to get 305.
Include the next digit (9) from the dividend after 305, then repeat: 3059 / 425

Advancing to step 6:
When dividing 3059 by 425, we get 7 with a remainder of 84.
Put 7 as the next digit of the answer. 
Result so far: 1907.0
Subtracting 2975 from 3059 leaves us with 84.
Append the next digit (8) from the dividend to 84 and continue with: 848 / 425

Advancing to step 7:
If we divide 848 by 425, we get 1 and a remainder of 423.
Use 1 as the next digit of our solution. 
Result so far: 19071.0
Deduct 425 from 848 and we're left with 423.
Append the next digit (8) from the dividend to 423 and continue with: 4238 / 425

Let's proceed to step 8:
If we divide 4238 by 425, we get 9 and a remainder of 413.
Record the quotient 9 as the next digit in the result. 
Result so far: 190719.0
The remainder is 413 after subtracting 3825 from 4238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Step 9:
4130 divided by 425 is 9 with a remainder of 305.
Use 9 as the next digit of our solution. 
Result so far: 190719.9
If we take 3825 away from 4130, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Let's proceed to step 10:
425 can be fit into 3050 7 times, resulting in a remainder of 75.
Record the quotient 7 as the next digit in the result. 
Result so far: 190719.97
Subtract 2975 from 3050 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 11:
The number 425 fits into 750 1 times, leaving a remainder of 325.
Record the quotient 1 as the next digit in the result. 
Result so far: 190719.971
Subtract 425 from 750 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

On to step 12:
425 goes into 3250 7 times with a remainder of 275.
Use 7 as the next digit of our solution. 
Result so far: 190719.9717
Subtracting 2975 from 3250 leaves us with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Advancing to step 13:
425 goes into 2750 6 times with a remainder of 200.
Put 6 as the next digit of the answer. 
Result so far: 190719.97176
Deduct 2550 from 2750 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 14:
425 can be fit into 2000 4 times, resulting in a remainder of 300.
Record the quotient 4 as the next digit in the result. 
Result so far: 190719.971764
Subtract 1700 from 2000 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 15:
The number 425 fits into 3000 7 times, leaving a remainder of 25.
The number 7 becomes the next digit in our result. 
Result so far: 190719.9717647
Deduct 2975 from 3000 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 16:
If we divide 250 by 425, we get 0 and a remainder of 250.
Write down 0 as next digit of the result. 
Result so far: 190719.9717647
If we subtract 0 from 250, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

The final result is 190719.9717647 with a remainder of 2.5e-07.
