We're dividing 57545576 by 438 
The aim is to understand the frequency of 438 in 57545576.

Step 1:
438 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 438

Let's proceed to step 2:
The number 438 fits into 57 0 times, leaving a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Append the next digit (5) from the dividend to 57 and continue with: 575 / 438

On to step 3:
If we divide 575 by 438, we get 1 and a remainder of 137.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 438 from 575 to get 137.
Include the next digit (4) from the dividend after 137, then repeat: 1374 / 438

Going ahead to step 4:
438 goes into 1374 3 times with a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 1314 from 1374 leaves us with 60.
Append the next digit (5) from the dividend to 60 and continue with: 605 / 438

Step 5:
If we divide 605 by 438, we get 1 and a remainder of 167.
Write down 1 as next digit of the result. 
Result so far: 131.0
Subtracting 438 from 605 leaves us with 167.
Include the next digit (5) from the dividend after 167, then repeat: 1675 / 438

On to step 6:
The number 438 fits into 1675 3 times, leaving a remainder of 361.
Record the quotient 3 as the next digit in the result. 
Result so far: 1313.0
If we take 1314 away from 1675, we end up with 361.
Grab the next digit (7) from the dividend, add it to 361, then carry on: 3617 / 438

On to step 7:
When dividing 3617 by 438, we get 8 with a remainder of 113.
Use 8 as the next digit of our solution. 
Result so far: 13138.0
Subtracting 3504 from 3617 leaves us with 113.
Include the next digit (6) from the dividend after 113, then repeat: 1136 / 438

Going ahead to step 8:
438 goes into 1136 2 times with a remainder of 260.
Put 2 as the next digit of the answer. 
Result so far: 131382.0
Subtract 876 from 1136 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 9:
2600 divided by 438 is 5 with a remainder of 410.
Use 5 as the next digit of our solution. 
Result so far: 131382.5
Subtract 2190 from 2600 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 10:
The number 438 fits into 4100 9 times, leaving a remainder of 158.
The number 9 becomes the next digit in our result. 
Result so far: 131382.59
If we subtract 3942 from 4100, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 11:
The number 438 fits into 1580 3 times, leaving a remainder of 266.
Write down 3 as next digit of the result. 
Result so far: 131382.593
Subtracting 1314 from 1580 leaves us with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Going ahead to step 12:
2660 divided by 438 is 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 131382.5936
Subtract 2628 from 2660 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 13:
320 divided by 438 is 0 with a remainder of 320.
Record the quotient 0 as the next digit in the result. 
Result so far: 131382.5936
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 14:
The number 438 fits into 3200 7 times, leaving a remainder of 134.
Write down 7 as next digit of the result. 
Result so far: 131382.593607
Deduct 3066 from 3200 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 15:
438 can be fit into 1340 3 times, resulting in a remainder of 26.
Use 3 as the next digit of our solution. 
Result so far: 131382.5936073
Subtracting 1314 from 1340 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 16:
438 goes into 260 0 times with a remainder of 260.
The next digit of our result is 0. 
Result so far: 131382.5936073
Subtract 0 from 260 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The final outcome is 131382.5936073, with a leftover of 2.6e-07.
