We're dividing 35838617 by 981 
The aim is to understand the frequency of 981 in 35838617.

Moving on to step 1:
If we divide 3 by 981, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 981

Step 2:
35 divided by 981 is 0 with a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Bring next digit (8) of the dividend behind the 35 and repeat the process: 358 / 981

Step 3:
If we divide 358 by 981, we get 0 and a remainder of 358.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 358 to get 358.
Append the next digit (3) from the dividend to 358 and continue with: 3583 / 981

On to step 4:
981 goes into 3583 3 times with a remainder of 640.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 2943 from 3583 leaves us with 640.
Append the next digit (8) from the dividend to 640 and continue with: 6408 / 981

On to step 5:
981 can be fit into 6408 6 times, resulting in a remainder of 522.
The next digit of our result is 6. 
Result so far: 36.0
If we take 5886 away from 6408, we end up with 522.
Take the next digit (6) from the dividend and append it to 522, then repeat: 5226 / 981

Advancing to step 6:
The number 981 fits into 5226 5 times, leaving a remainder of 321.
The next digit of our result is 5. 
Result so far: 365.0
The remainder is 321 after subtracting 4905 from 5226.
Append the next digit (1) from the dividend to 321 and continue with: 3211 / 981

Step 7:
3211 divided by 981 is 3 with a remainder of 268.
Write down 3 as next digit of the result. 
Result so far: 3653.0
Deduct 2943 from 3211 and we're left with 268.
Bring next digit (7) of the dividend behind the 268 and repeat the process: 2687 / 981

Let's proceed to step 8:
2687 divided by 981 is 2 with a remainder of 725.
Write down 2 as next digit of the result. 
Result so far: 36532.0
If we subtract 1962 from 2687, we get 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Going ahead to step 9:
When dividing 7250 by 981, we get 7 with a remainder of 383.
The next digit of our result is 7. 
Result so far: 36532.7
If we take 6867 away from 7250, we end up with 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Advancing to step 10:
The number 981 fits into 3830 3 times, leaving a remainder of 887.
Put 3 as the next digit of the answer. 
Result so far: 36532.73
If we take 2943 away from 3830, we end up with 887.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8870, and continue the process.

Step 11:
981 goes into 8870 9 times with a remainder of 41.
The next digit of our result is 9. 
Result so far: 36532.739
If we take 8829 away from 8870, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 12:
When dividing 410 by 981, we get 0 with a remainder of 410.
Record the quotient 0 as the next digit in the result. 
Result so far: 36532.739
Subtract 0 from 410 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Moving on to step 13:
The number 981 fits into 4100 4 times, leaving a remainder of 176.
Use 4 as the next digit of our solution. 
Result so far: 36532.73904
Subtract 3924 from 4100 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 14:
When dividing 1760 by 981, we get 1 with a remainder of 779.
Put 1 as the next digit of the answer. 
Result so far: 36532.739041
If we take 981 away from 1760, we end up with 779.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7790, and continue the process.

Step 15:
If we divide 7790 by 981, we get 7 and a remainder of 923.
The next digit of our result is 7. 
Result so far: 36532.7390417
Deduct 6867 from 7790 and we're left with 923.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9230, and continue the process.

Moving on to step 16:
When dividing 9230 by 981, we get 9 with a remainder of 401.
The next digit of our result is 9. 
Result so far: 36532.73904179
Deduct 8829 from 9230 and we're left with 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

The final result is 36532.73904179 with a remainder of 4.01e-07.
