42211695 ÷ 438 
The aim is to understand the frequency of 438 in 42211695.

On to step 1:
438 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 438

Going ahead to step 2:
438 can be fit into 42 0 times, resulting in a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Bring next digit (2) of the dividend behind the 42 and repeat the process: 422 / 438

Step 3:
The number 438 fits into 422 0 times, leaving a remainder of 422.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 422 leaves us with 422.
Bring next digit (1) of the dividend behind the 422 and repeat the process: 4221 / 438

Step 4:
If we divide 4221 by 438, we get 9 and a remainder of 279.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 3942 from 4221 to get 279.
Append the next digit (1) from the dividend to 279 and continue with: 2791 / 438

Step 5:
When dividing 2791 by 438, we get 6 with a remainder of 163.
Write down 6 as next digit of the result. 
Result so far: 96.0
Subtract 2628 from 2791 to get 163.
Bring next digit (6) of the dividend behind the 163 and repeat the process: 1636 / 438

Going ahead to step 6:
438 can be fit into 1636 3 times, resulting in a remainder of 322.
Write down 3 as next digit of the result. 
Result so far: 963.0
If we take 1314 away from 1636, we end up with 322.
Append the next digit (9) from the dividend to 322 and continue with: 3229 / 438

Let's proceed to step 7:
3229 divided by 438 is 7 with a remainder of 163.
Record the quotient 7 as the next digit in the result. 
Result so far: 9637.0
Deduct 3066 from 3229 and we're left with 163.
Take the next digit (5) from the dividend and append it to 163, then repeat: 1635 / 438

Moving on to step 8:
If we divide 1635 by 438, we get 3 and a remainder of 321.
The number 3 becomes the next digit in our result. 
Result so far: 96373.0
If we take 1314 away from 1635, we end up with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Going ahead to step 9:
If we divide 3210 by 438, we get 7 and a remainder of 144.
The next digit of our result is 7. 
Result so far: 96373.7
If we take 3066 away from 3210, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 10:
438 goes into 1440 3 times with a remainder of 126.
Record the quotient 3 as the next digit in the result. 
Result so far: 96373.73
Deduct 1314 from 1440 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Going ahead to step 11:
When dividing 1260 by 438, we get 2 with a remainder of 384.
The next digit of our result is 2. 
Result so far: 96373.732
If we take 876 away from 1260, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 12:
438 can be fit into 3840 8 times, resulting in a remainder of 336.
Record the quotient 8 as the next digit in the result. 
Result so far: 96373.7328
If we subtract 3504 from 3840, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 13:
438 goes into 3360 7 times with a remainder of 294.
The number 7 becomes the next digit in our result. 
Result so far: 96373.73287
Deduct 3066 from 3360 and we're left with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Advancing to step 14:
If we divide 2940 by 438, we get 6 and a remainder of 312.
Record the quotient 6 as the next digit in the result. 
Result so far: 96373.732876
The remainder is 312 after subtracting 2628 from 2940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Step 15:
438 can be fit into 3120 7 times, resulting in a remainder of 54.
The next digit of our result is 7. 
Result so far: 96373.7328767
Deduct 3066 from 3120 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 16:
438 goes into 540 1 times with a remainder of 102.
The number 1 becomes the next digit in our result. 
Result so far: 96373.73287671
If we take 438 away from 540, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

The final outcome is 96373.73287671, with a leftover of 1.02e-07.
