57215641 ÷ 424 
The aim is to understand the frequency of 424 in 57215641.

On to step 1:
The number 424 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 424

Advancing to step 2:
If we divide 57 by 424, we get 0 and a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Bring next digit (2) of the dividend behind the 57 and repeat the process: 572 / 424

Advancing to step 3:
If we divide 572 by 424, we get 1 and a remainder of 148.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 148 after subtracting 424 from 572.
Take the next digit (1) from the dividend and append it to 148, then repeat: 1481 / 424

Step 4:
The number 424 fits into 1481 3 times, leaving a remainder of 209.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 1272 from 1481 and we're left with 209.
Fetch the next digit (5) from the dividend, attach it to 209 and continue: 2095 / 424

Moving on to step 5:
2095 divided by 424 is 4 with a remainder of 399.
Record the quotient 4 as the next digit in the result. 
Result so far: 134.0
Subtract 1696 from 2095 to get 399.
Bring next digit (6) of the dividend behind the 399 and repeat the process: 3996 / 424

Let's proceed to step 6:
424 can be fit into 3996 9 times, resulting in a remainder of 180.
Write down 9 as next digit of the result. 
Result so far: 1349.0
The remainder is 180 after subtracting 3816 from 3996.
Include the next digit (4) from the dividend after 180, then repeat: 1804 / 424

On to step 7:
The number 424 fits into 1804 4 times, leaving a remainder of 108.
Write down 4 as next digit of the result. 
Result so far: 13494.0
If we subtract 1696 from 1804, we get 108.
Bring next digit (1) of the dividend behind the 108 and repeat the process: 1081 / 424

Step 8:
When dividing 1081 by 424, we get 2 with a remainder of 233.
Use 2 as the next digit of our solution. 
Result so far: 134942.0
Subtract 848 from 1081 to get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Step 9:
424 goes into 2330 5 times with a remainder of 210.
Record the quotient 5 as the next digit in the result. 
Result so far: 134942.5
If we take 2120 away from 2330, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 10:
424 can be fit into 2100 4 times, resulting in a remainder of 404.
Use 4 as the next digit of our solution. 
Result so far: 134942.54
The remainder is 404 after subtracting 1696 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Moving on to step 11:
4040 divided by 424 is 9 with a remainder of 224.
Write down 9 as next digit of the result. 
Result so far: 134942.549
If we subtract 3816 from 4040, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 12:
424 can be fit into 2240 5 times, resulting in a remainder of 120.
The number 5 becomes the next digit in our result. 
Result so far: 134942.5495
Subtracting 2120 from 2240 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 13:
When dividing 1200 by 424, we get 2 with a remainder of 352.
The number 2 becomes the next digit in our result. 
Result so far: 134942.54952
If we subtract 848 from 1200, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Advancing to step 14:
When dividing 3520 by 424, we get 8 with a remainder of 128.
The next digit of our result is 8. 
Result so far: 134942.549528
If we take 3392 away from 3520, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 15:
1280 divided by 424 is 3 with a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 134942.5495283
Deduct 1272 from 1280 and we're left with 8.
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 16:
When dividing 80 by 424, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 134942.5495283
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Our division results in 134942.5495283 with a remaining 8e-08.
