We look at the division of 84160937 by 981 
The aim is to understand the frequency of 981 in 84160937.

Moving on to step 1:
8 divided by 981 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 981

Moving on to step 2:
981 can be fit into 84 0 times, resulting in a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Fetch the next digit (1) from the dividend, attach it to 84 and continue: 841 / 981

On to step 3:
981 can be fit into 841 0 times, resulting in a remainder of 841.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 841 to get 841.
Bring next digit (6) of the dividend behind the 841 and repeat the process: 8416 / 981

On to step 4:
981 can be fit into 8416 8 times, resulting in a remainder of 568.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 7848 from 8416 leaves us with 568.
Bring next digit (0) of the dividend behind the 568 and repeat the process: 5680 / 981

Going ahead to step 5:
If we divide 5680 by 981, we get 5 and a remainder of 775.
The next digit of our result is 5. 
Result so far: 85.0
If we subtract 4905 from 5680, we get 775.
Bring next digit (9) of the dividend behind the 775 and repeat the process: 7759 / 981

On to step 6:
981 goes into 7759 7 times with a remainder of 892.
Write down 7 as next digit of the result. 
Result so far: 857.0
Subtracting 6867 from 7759 leaves us with 892.
Include the next digit (3) from the dividend after 892, then repeat: 8923 / 981

On to step 7:
When dividing 8923 by 981, we get 9 with a remainder of 94.
Write down 9 as next digit of the result. 
Result so far: 8579.0
The remainder is 94 after subtracting 8829 from 8923.
Append the next digit (7) from the dividend to 94 and continue with: 947 / 981

Step 8:
If we divide 947 by 981, we get 0 and a remainder of 947.
Put 0 as the next digit of the answer. 
Result so far: 85790.0
If we subtract 0 from 947, we get 947.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9470, and continue the process.

Moving on to step 9:
When dividing 9470 by 981, we get 9 with a remainder of 641.
The next digit of our result is 9. 
Result so far: 85790.9
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.

On to step 10:
981 goes into 6410 6 times with a remainder of 524.
The next digit of our result is 6. 
Result so far: 85790.96
Deduct 5886 from 6410 and we're left with 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 11:
5240 divided by 981 is 5 with a remainder of 335.
The next digit of our result is 5. 
Result so far: 85790.965
If we take 4905 away from 5240, we end up 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.

Going ahead to step 12:
If we divide 3350 by 981, we get 3 and a remainder of 407.
Put 3 as the next digit of the answer. 
Result so far: 85790.9653
If we subtract 2943 from 3350, we get 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Moving on to step 13:
981 goes into 4070 4 times with a remainder of 146.
Put 4 as the next digit of the answer. 
Result so far: 85790.96534
Subtracting 3924 from 4070 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Going ahead to step 14:
1460 divided by 981 is 1 with a remainder of 479.
The number 1 becomes the next digit in our result. 
Result so far: 85790.965341
If we take 981 away from 1460, we end up with 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Advancing to step 15:
981 can be fit into 4790 4 times, resulting in a remainder of 866.
Record the quotient 4 as the next digit in the result. 
Result so far: 85790.9653414
Deduct 3924 from 4790 and we're left with 866.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8660, and continue the process.

Let's proceed to step 16:
8660 divided by 981 is 8 with a remainder of 812.
The number 8 becomes the next digit in our result. 
Result so far: 85790.96534148
Subtracting 7848 from 8660 leaves us with 812.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8120, and continue the process.

The quotient of the division is 85790.96534148, and the remainder is 8.12e-07.
