We're dividing 77313633 by 981 
The aim is to understand the frequency of 981 in 77313633.

Let's proceed to step 1:
981 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 981

Step 2:
If we divide 77 by 981, we get 0 and a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Grab the next digit (3) from the dividend, add it to 77, then carry on: 773 / 981

Let's proceed to step 3:
The number 981 fits into 773 0 times, leaving a remainder of 773.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 773 after subtracting 0 from 773.
Grab the next digit (1) from the dividend, add it to 773, then carry on: 7731 / 981

Step 4:
7731 divided by 981 is 7 with a remainder of 864.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 6867 away from 7731, we end up with 864.
Grab the next digit (3) from the dividend, add it to 864, then carry on: 8643 / 981

On to step 5:
If we divide 8643 by 981, we get 8 and a remainder of 795.
Write down 8 as next digit of the result. 
Result so far: 78.0
Deduct 7848 from 8643 and we're left with 795.
Append the next digit (6) from the dividend to 795 and continue with: 7956 / 981

On to step 6:
If we divide 7956 by 981, we get 8 and a remainder of 108.
Use 8 as the next digit of our solution. 
Result so far: 788.0
If we take 7848 away from 7956, we end up with 108.
Take the next digit (3) from the dividend and append it to 108, then repeat: 1083 / 981

Let's proceed to step 7:
The number 981 fits into 1083 1 times, leaving a remainder of 102.
Write down 1 as next digit of the result. 
Result so far: 7881.0
Deduct 981 from 1083 and we're left with 102.
Include the next digit (3) from the dividend after 102, then repeat: 1023 / 981

Moving on to step 8:
1023 divided by 981 is 1 with a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 78811.0
Subtracting 981 from 1023 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 9:
981 goes into 420 0 times with a remainder of 420.
The next digit of our result is 0. 
Result so far: 78811.0
Deduct 0 from 420 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 10:
When dividing 4200 by 981, we get 4 with a remainder of 276.
The number 4 becomes the next digit in our result. 
Result so far: 78811.04
The remainder is 276 after subtracting 3924 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Advancing to step 11:
981 can be fit into 2760 2 times, resulting in a remainder of 798.
Put 2 as the next digit of the answer. 
Result so far: 78811.042
Subtract 1962 from 2760 to get 798.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7980, and continue the process.

On to step 12:
981 goes into 7980 8 times with a remainder of 132.
The next digit of our result is 8. 
Result so far: 78811.0428
If we take 7848 away from 7980, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 13:
981 goes into 1320 1 times with a remainder of 339.
Write down 1 as next digit of the result. 
Result so far: 78811.04281
If we subtract 981 from 1320, we get 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Advancing to step 14:
The number 981 fits into 3390 3 times, leaving a remainder of 447.
Put 3 as the next digit of the answer. 
Result so far: 78811.042813
If we take 2943 away from 3390, we end up with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Moving on to step 15:
981 can be fit into 4470 4 times, resulting in a remainder of 546.
Put 4 as the next digit of the answer. 
Result so far: 78811.0428134
Deduct 3924 from 4470 and we're left with 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Moving on to step 16:
If we divide 5460 by 981, we get 5 and a remainder of 555.
The next digit of our result is 5. 
Result so far: 78811.04281345
If we subtract 4905 from 5460, we get 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

After the division, we end up with 78811.04281345 and a remainder of 5.55e-07.
