We divide 13828493 by 981
The aim is to understand the frequency of 981 in 13828493.

Step 1:
When dividing 1 by 981, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 981

Moving on to step 2:
13 divided by 981 is 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 981

Step 3:
When dividing 138 by 981, we get 0 with a remainder of 138.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 138, we end up with 138.
Take the next digit (2) from the dividend and append it to 138, then repeat: 1382 / 981

Step 4:
The number 981 fits into 1382 1 times, leaving a remainder of 401.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 981 from 1382, we get 401.
Fetch the next digit (8) from the dividend, attach it to 401 and continue: 4018 / 981

Let's proceed to step 5:
981 can be fit into 4018 4 times, resulting in a remainder of 94.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 94 after subtracting 3924 from 4018.
Take the next digit (4) from the dividend and append it to 94, then repeat: 944 / 981

Moving on to step 6:
944 divided by 981 is 0 with a remainder of 944.
Use 0 as the next digit of our solution. 
Result so far: 140.0
The remainder is 944 after subtracting 0 from 944.
Take the next digit (9) from the dividend and append it to 944, then repeat: 9449 / 981

Going ahead to step 7:
981 goes into 9449 9 times with a remainder of 620.
The number 9 becomes the next digit in our result. 
Result so far: 1409.0
Subtracting 8829 from 9449 leaves us with 620.
Append the next digit (3) from the dividend to 620 and continue with: 6203 / 981

Let's proceed to step 8:
When dividing 6203 by 981, we get 6 with a remainder of 317.
Write down 6 as next digit of the result. 
Result so far: 14096.0
If we take 5886 away from 6203, we end up with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Going ahead to step 9:
The number 981 fits into 3170 3 times, leaving a remainder of 227.
The number 3 becomes the next digit in our result. 
Result so far: 14096.3
The remainder is 227 after subtracting 2943 from 3170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Let's proceed to step 10:
The number 981 fits into 2270 2 times, leaving a remainder of 308.
Use 2 as the next digit of our solution. 
Result so far: 14096.32
If we subtract 1962 from 2270, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Advancing to step 11:
If we divide 3080 by 981, we get 3 and a remainder of 137.
Put 3 as the next digit of the answer. 
Result so far: 14096.323
The remainder is 137 after subtracting 2943 from 3080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Step 12:
981 goes into 1370 1 times with a remainder of 389.
The number 1 becomes the next digit in our result. 
Result so far: 14096.3231
If we subtract 981 from 1370, we get 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Moving on to step 13:
3890 divided by 981 is 3 with a remainder of 947.
Put 3 as the next digit of the answer. 
Result so far: 14096.32313
Deduct 2943 from 3890 and we're left with 947.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9470, and continue the process.

Step 14:
The number 981 fits into 9470 9 times, leaving a remainder of 641.
The next digit of our result is 9. 
Result so far: 14096.323139
Deduct 8829 from 9470 and we're left with 641.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6410, and continue the process.

Let's proceed to step 15:
981 goes into 6410 6 times with a remainder of 524.
The next digit of our result is 6. 
Result so far: 14096.3231396
Subtract 5886 from 6410 to get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

On to step 16:
5240 divided by 981 is 5 with a remainder of 335.
The number 5 becomes the next digit in our result. 
Result so far: 14096.32313965
Subtracting 4905 from 5240 leaves us with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

The final result is 14096.32313965 with a remainder of 3.35e-07.
