29821400 divided by 398 
The aim is to understand the frequency of 398 in 29821400.

Step 1:
398 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 398

Advancing to step 2:
398 goes into 29 0 times with a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Grab the next digit (8) from the dividend, add it to 29, then carry on: 298 / 398

Advancing to step 3:
When dividing 298 by 398, we get 0 with a remainder of 298.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 298 and we're left with 298.
Include the next digit (2) from the dividend after 298, then repeat: 2982 / 398

Step 4:
398 goes into 2982 7 times with a remainder of 196.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 2786 from 2982 leaves us with 196.
Bring next digit (1) of the dividend behind the 196 and repeat the process: 1961 / 398

Step 5:
When dividing 1961 by 398, we get 4 with a remainder of 369.
Put 4 as the next digit of the answer. 
Result so far: 74.0
If we take 1592 away from 1961, we end up with 369.
Grab the next digit (4) from the dividend, add it to 369, then carry on: 3694 / 398

Going ahead to step 6:
If we divide 3694 by 398, we get 9 and a remainder of 112.
Put 9 as the next digit of the answer. 
Result so far: 749.0
Subtract 3582 from 3694 to get 112.
Grab the next digit (0) from the dividend, add it to 112, then carry on: 1120 / 398

Moving on to step 7:
When dividing 1120 by 398, we get 2 with a remainder of 324.
The next digit of our result is 2. 
Result so far: 7492.0
Deduct 796 from 1120 and we're left with 324.
Grab the next digit (0) from the dividend, add it to 324, then carry on: 3240 / 398

Let's proceed to step 8:
3240 divided by 398 is 8 with a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 74928.0
Subtracting 3184 from 3240 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 9:
398 can be fit into 560 1 times, resulting in a remainder of 162.
The number 1 becomes the next digit in our result. 
Result so far: 74928.1
If we take 398 away from 560, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Advancing to step 10:
398 can be fit into 1620 4 times, resulting in a remainder of 28.
The next digit of our result is 4. 
Result so far: 74928.14
Subtracting 1592 from 1620 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 11:
When dividing 280 by 398, we get 0 with a remainder of 280.
Put 0 as the next digit of the answer. 
Result so far: 74928.14
The remainder is 280 after subtracting 0 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 12:
2800 divided by 398 is 7 with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 74928.1407
If we subtract 2786 from 2800, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 13:
If we divide 140 by 398, we get 0 and a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 74928.1407
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 14:
1400 divided by 398 is 3 with a remainder of 206.
Write down 3 as next digit of the result. 
Result so far: 74928.140703
If we subtract 1194 from 1400, we get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

On to step 15:
398 can be fit into 2060 5 times, resulting in a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 74928.1407035
Deduct 1990 from 2060 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 16:
If we divide 700 by 398, we get 1 and a remainder of 302.
Record the quotient 1 as the next digit in the result. 
Result so far: 74928.14070351
Deduct 398 from 700 and we're left with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

The quotient of the division is 74928.14070351, and the remainder is 3.02e-07.
