Let's divide 3838638 by 772
The aim is to understand the frequency of 772 in 3838638.

Let's proceed to step 1:
When dividing 3 by 772, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 772

Advancing to step 2:
772 can be fit into 38 0 times, resulting in a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Take the next digit (3) from the dividend and append it to 38, then repeat: 383 / 772

Going ahead to step 3:
If we divide 383 by 772, we get 0 and a remainder of 383.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 383 to get 383.
Include the next digit (8) from the dividend after 383, then repeat: 3838 / 772

Advancing to step 4:
When dividing 3838 by 772, we get 4 with a remainder of 750.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 3088 away from 3838, we end up with 750.
Fetch the next digit (6) from the dividend, attach it to 750 and continue: 7506 / 772

Moving on to step 5:
The number 772 fits into 7506 9 times, leaving a remainder of 558.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
If we take 6948 away from 7506, we end up with 558.
Fetch the next digit (3) from the dividend, attach it to 558 and continue: 5583 / 772

Let's proceed to step 6:
772 can be fit into 5583 7 times, resulting in a remainder of 179.
Record the quotient 7 as the next digit in the result. 
Result so far: 497.0
Deduct 5404 from 5583 and we're left with 179.
Append the next digit (8) from the dividend to 179 and continue with: 1798 / 772

Advancing to step 7:
If we divide 1798 by 772, we get 2 and a remainder of 254.
Write down 2 as next digit of the result. 
Result so far: 4972.0
Subtracting 1544 from 1798 leaves us with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

On to step 8:
If we divide 2540 by 772, we get 3 and a remainder of 224.
Use 3 as the next digit of our solution. 
Result so far: 4972.3
If we take 2316 away from 2540, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 9:
When dividing 2240 by 772, we get 2 with a remainder of 696.
Write down 2 as next digit of the result. 
Result so far: 4972.32
Deduct 1544 from 2240 and we're left with 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Moving on to step 10:
772 goes into 6960 9 times with a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 4972.329
Subtract 6948 from 6960 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
772 goes into 120 0 times with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 4972.329
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 12:
The number 772 fits into 1200 1 times, leaving a remainder of 428.
Use 1 as the next digit of our solution. 
Result so far: 4972.32901
Subtract 772 from 1200 to get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Going ahead to step 13:
4280 divided by 772 is 5 with a remainder of 420.
The number 5 becomes the next digit in our result. 
Result so far: 4972.329015
Subtract 3860 from 4280 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Step 14:
4200 divided by 772 is 5 with a remainder of 340.
Use 5 as the next digit of our solution. 
Result so far: 4972.3290155
If we subtract 3860 from 4200, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

After the division, we end up with 4972.3290155 and a remainder of 3.4e-06.
