We're dividing 37489828 by 981 
The aim is to understand the frequency of 981 in 37489828.

Advancing to step 1:
If we divide 3 by 981, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 981

Going ahead to step 2:
If we divide 37 by 981, we get 0 and a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Append the next digit (4) from the dividend to 37 and continue with: 374 / 981

On to step 3:
If we divide 374 by 981, we get 0 and a remainder of 374.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 374 after subtracting 0 from 374.
Grab the next digit (8) from the dividend, add it to 374, then carry on: 3748 / 981

Advancing to step 4:
981 can be fit into 3748 3 times, resulting in a remainder of 805.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 805 after subtracting 2943 from 3748.
Grab the next digit (9) from the dividend, add it to 805, then carry on: 8059 / 981

On to step 5:
The number 981 fits into 8059 8 times, leaving a remainder of 211.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
If we subtract 7848 from 8059, we get 211.
Bring next digit (8) of the dividend behind the 211 and repeat the process: 2118 / 981

Going ahead to step 6:
If we divide 2118 by 981, we get 2 and a remainder of 156.
The next digit of our result is 2. 
Result so far: 382.0
Subtract 1962 from 2118 to get 156.
Fetch the next digit (2) from the dividend, attach it to 156 and continue: 1562 / 981

Advancing to step 7:
If we divide 1562 by 981, we get 1 and a remainder of 581.
Record the quotient 1 as the next digit in the result. 
Result so far: 3821.0
Subtracting 981 from 1562 leaves us with 581.
Fetch the next digit (8) from the dividend, attach it to 581 and continue: 5818 / 981

On to step 8:
5818 divided by 981 is 5 with a remainder of 913.
Put 5 as the next digit of the answer. 
Result so far: 38215.0
Subtracting 4905 from 5818 leaves us with 913.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9130, and continue the process.

On to step 9:
981 goes into 9130 9 times with a remainder of 301.
Use 9 as the next digit of our solution. 
Result so far: 38215.9
Subtract 8829 from 9130 to get 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Advancing to step 10:
If we divide 3010 by 981, we get 3 and a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 38215.93
The remainder is 67 after subtracting 2943 from 3010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 11:
When dividing 670 by 981, we get 0 with a remainder of 670.
Use 0 as the next digit of our solution. 
Result so far: 38215.93
If we subtract 0 from 670, we get 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

On to step 12:
981 goes into 6700 6 times with a remainder of 814.
Record the quotient 6 as the next digit in the result. 
Result so far: 38215.9306
If we subtract 5886 from 6700, we get 814.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8140, and continue the process.

Step 13:
8140 divided by 981 is 8 with a remainder of 292.
The number 8 becomes the next digit in our result. 
Result so far: 38215.93068
Subtracting 7848 from 8140 leaves us with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Moving on to step 14:
The number 981 fits into 2920 2 times, leaving a remainder of 958.
Write down 2 as next digit of the result. 
Result so far: 38215.930682
Subtract 1962 from 2920 to get 958.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9580, and continue the process.

Advancing to step 15:
981 goes into 9580 9 times with a remainder of 751.
The number 9 becomes the next digit in our result. 
Result so far: 38215.9306829
Subtracting 8829 from 9580 leaves us with 751.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7510, and continue the process.

On to step 16:
981 can be fit into 7510 7 times, resulting in a remainder of 643.
Put 7 as the next digit of the answer. 
Result so far: 38215.93068297
The remainder is 643 after subtracting 6867 from 7510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6430, and continue the process.

In conclusion, the division gives 38215.93068297 with a balance of 6.43e-07.
