76632501 divided by 398 
The aim is to understand the frequency of 398 in 76632501.

Step 1:
398 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 398

Going ahead to step 2:
The number 398 fits into 76 0 times, leaving a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 76, we end up with 76.
Take the next digit (6) from the dividend and append it to 76, then repeat: 766 / 398

Step 3:
766 divided by 398 is 1 with a remainder of 368.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 398 from 766 to get 368.
Include the next digit (3) from the dividend after 368, then repeat: 3683 / 398

Going ahead to step 4:
The number 398 fits into 3683 9 times, leaving a remainder of 101.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we take 3582 away from 3683, we end up with 101.
Take the next digit (2) from the dividend and append it to 101, then repeat: 1012 / 398

On to step 5:
The number 398 fits into 1012 2 times, leaving a remainder of 216.
The number 2 becomes the next digit in our result. 
Result so far: 192.0
If we subtract 796 from 1012, we get 216.
Append the next digit (5) from the dividend to 216 and continue with: 2165 / 398

Advancing to step 6:
398 goes into 2165 5 times with a remainder of 175.
Put 5 as the next digit of the answer. 
Result so far: 1925.0
If we take 1990 away from 2165, we end up with 175.
Include the next digit (0) from the dividend after 175, then repeat: 1750 / 398

Let's proceed to step 7:
398 can be fit into 1750 4 times, resulting in a remainder of 158.
Use 4 as the next digit of our solution. 
Result so far: 19254.0
Subtracting 1592 from 1750 leaves us with 158.
Take the next digit (1) from the dividend and append it to 158, then repeat: 1581 / 398

Let's proceed to step 8:
When dividing 1581 by 398, we get 3 with a remainder of 387.
The next digit of our result is 3. 
Result so far: 192543.0
Subtract 1194 from 1581 to get 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Advancing to step 9:
If we divide 3870 by 398, we get 9 and a remainder of 288.
The number 9 becomes the next digit in our result. 
Result so far: 192543.9
If we take 3582 away from 3870, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 10:
398 goes into 2880 7 times with a remainder of 94.
Write down 7 as next digit of the result. 
Result so far: 192543.97
If we take 2786 away from 2880, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 11:
398 can be fit into 940 2 times, resulting in a remainder of 144.
Put 2 as the next digit of the answer. 
Result so far: 192543.972
The remainder is 144 after subtracting 796 from 940.
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 12:
When dividing 1440 by 398, we get 3 with a remainder of 246.
Use 3 as the next digit of our solution. 
Result so far: 192543.9723
Deduct 1194 from 1440 and we're left with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Step 13:
When dividing 2460 by 398, we get 6 with a remainder of 72.
The next digit of our result is 6. 
Result so far: 192543.97236
If we subtract 2388 from 2460, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 14:
720 divided by 398 is 1 with a remainder of 322.
Record the quotient 1 as the next digit in the result. 
Result so far: 192543.972361
Subtracting 398 from 720 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Let's proceed to step 15:
When dividing 3220 by 398, we get 8 with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 192543.9723618
The remainder is 36 after subtracting 3184 from 3220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 16:
When dividing 360 by 398, we get 0 with a remainder of 360.
The number 0 becomes the next digit in our result. 
Result so far: 192543.9723618
Subtracting 0 from 360 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

After the division, we end up with 192543.9723618 and a remainder of 3.6e-07.
