87061772 ÷ 426 
The aim is to understand the frequency of 426 in 87061772.

Let's proceed to step 1:
The number 426 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 426

Step 2:
87 divided by 426 is 0 with a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Include the next digit (0) from the dividend after 87, then repeat: 870 / 426

Step 3:
When dividing 870 by 426, we get 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 852 from 870, we get 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 426

Let's proceed to step 4:
When dividing 186 by 426, we get 0 with a remainder of 186.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Deduct 0 from 186 and we're left with 186.
Bring next digit (1) of the dividend behind the 186 and repeat the process: 1861 / 426

Let's proceed to step 5:
1861 divided by 426 is 4 with a remainder of 157.
Put 4 as the next digit of the answer. 
Result so far: 204.0
Subtract 1704 from 1861 to get 157.
Take the next digit (7) from the dividend and append it to 157, then repeat: 1577 / 426

Going ahead to step 6:
1577 divided by 426 is 3 with a remainder of 299.
Write down 3 as next digit of the result. 
Result so far: 2043.0
If we take 1278 away from 1577, we end up with 299.
Include the next digit (7) from the dividend after 299, then repeat: 2997 / 426

Let's proceed to step 7:
2997 divided by 426 is 7 with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 20437.0
Deduct 2982 from 2997 and we're left with 15.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 426

Step 8:
When dividing 152 by 426, we get 0 with a remainder of 152.
The number 0 becomes the next digit in our result. 
Result so far: 204370.0
Subtracting 0 from 152 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 9:
When dividing 1520 by 426, we get 3 with a remainder of 242.
Put 3 as the next digit of the answer. 
Result so far: 204370.3
If we subtract 1278 from 1520, we get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

On to step 10:
426 goes into 2420 5 times with a remainder of 290.
Use 5 as the next digit of our solution. 
Result so far: 204370.35
If we subtract 2130 from 2420, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Step 11:
426 goes into 2900 6 times with a remainder of 344.
The number 6 becomes the next digit in our result. 
Result so far: 204370.356
If we take 2556 away from 2900, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Moving on to step 12:
When dividing 3440 by 426, we get 8 with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 204370.3568
The remainder is 32 after subtracting 3408 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 13:
426 can be fit into 320 0 times, resulting in a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 204370.3568
Subtract 0 from 320 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 14:
426 can be fit into 3200 7 times, resulting in a remainder of 218.
The number 7 becomes the next digit in our result. 
Result so far: 204370.356807
Subtracting 2982 from 3200 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

On to step 15:
If we divide 2180 by 426, we get 5 and a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 204370.3568075
If we subtract 2130 from 2180, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 16:
When dividing 500 by 426, we get 1 with a remainder of 74.
The next digit of our result is 1. 
Result so far: 204370.35680751
If we take 426 away from 500, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

The final result is 204370.35680751 with a remainder of 7.4e-08.
