We're dividing 6210810 by 438 
The aim is to understand the frequency of 438 in 6210810.

Moving on to step 1:
6 divided by 438 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 438

Going ahead to step 2:
438 goes into 62 0 times with a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 62, we end up with 62.
Take the next digit (1) from the dividend and append it to 62, then repeat: 621 / 438

Going ahead to step 3:
When dividing 621 by 438, we get 1 with a remainder of 183.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 438 from 621 and we're left with 183.
Fetch the next digit (0) from the dividend, attach it to 183 and continue: 1830 / 438

Let's proceed to step 4:
1830 divided by 438 is 4 with a remainder of 78.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 1752 from 1830 leaves us with 78.
Grab the next digit (8) from the dividend, add it to 78, then carry on: 788 / 438

On to step 5:
The number 438 fits into 788 1 times, leaving a remainder of 350.
The next digit of our result is 1. 
Result so far: 141.0
If we subtract 438 from 788, we get 350.
Grab the next digit (1) from the dividend, add it to 350, then carry on: 3501 / 438

On to step 6:
If we divide 3501 by 438, we get 7 and a remainder of 435.
Put 7 as the next digit of the answer. 
Result so far: 1417.0
If we take 3066 away from 3501, we end up with 435.
Fetch the next digit (0) from the dividend, attach it to 435 and continue: 4350 / 438

Let's proceed to step 7:
If we divide 4350 by 438, we get 9 and a remainder of 408.
The number 9 becomes the next digit in our result. 
Result so far: 14179.0
If we take 3942 away from 4350, we end up with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Moving on to step 8:
The number 438 fits into 4080 9 times, leaving a remainder of 138.
Record the quotient 9 as the next digit in the result. 
Result so far: 14179.9
If we take 3942 away from 4080, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

On to step 9:
438 goes into 1380 3 times with a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 14179.93
If we subtract 1314 from 1380, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 10:
438 goes into 660 1 times with a remainder of 222.
Put 1 as the next digit of the answer. 
Result so far: 14179.931
If we subtract 438 from 660, we get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Advancing to step 11:
When dividing 2220 by 438, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 14179.9315
The remainder is 30 after subtracting 2190 from 2220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
438 can be fit into 300 0 times, resulting in a remainder of 300.
The next digit of our result is 0. 
Result so far: 14179.9315
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 13:
When dividing 3000 by 438, we get 6 with a remainder of 372.
Record the quotient 6 as the next digit in the result. 
Result so far: 14179.931506
Deduct 2628 from 3000 and we're left with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Moving on to step 14:
3720 divided by 438 is 8 with a remainder of 216.
Write down 8 as next digit of the result. 
Result so far: 14179.9315068
The remainder is 216 after subtracting 3504 from 3720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 15:
The number 438 fits into 2160 4 times, leaving a remainder of 408.
The next digit of our result is 4. 
Result so far: 14179.93150684
If we subtract 1752 from 2160, we get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

The quotient of the division is 14179.93150684, and the remainder is 4.08e-07.
