We divide 153893 by 77
The aim is to understand the frequency of 77 in 153893.

On to step 1:
77 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 77

Moving on to step 2:
If we divide 15 by 77, we get 0 and a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 77

Step 3:
When dividing 153 by 77, we get 1 with a remainder of 76.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 77 from 153 leaves us with 76.
Fetch the next digit (8) from the dividend, attach it to 76 and continue: 768 / 77

Advancing to step 4:
768 divided by 77 is 9 with a remainder of 75.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Deduct 693 from 768 and we're left with 75.
Bring next digit (9) of the dividend behind the 75 and repeat the process: 759 / 77

On to step 5:
77 goes into 759 9 times with a remainder of 66.
The number 9 becomes the next digit in our result. 
Result so far: 199.0
The remainder is 66 after subtracting 693 from 759.
Append the next digit (3) from the dividend to 66 and continue with: 663 / 77

Step 6:
The number 77 fits into 663 8 times, leaving a remainder of 47.
Write down 8 as next digit of the result. 
Result so far: 1998.0
Subtracting 616 from 663 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 7:
77 can be fit into 470 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 1998.6
If we take 462 away from 470, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
77 goes into 80 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1998.61
Deduct 77 from 80 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
30 divided by 77 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 1998.61
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
The number 77 fits into 300 3 times, leaving a remainder of 69.
Use 3 as the next digit of our solution. 
Result so far: 1998.6103
If we subtract 231 from 300, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 11:
When dividing 690 by 77, we get 8 with a remainder of 74.
Put 8 as the next digit of the answer. 
Result so far: 1998.61038
If we take 616 away from 690, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 12:
If we divide 740 by 77, we get 9 and a remainder of 47.
Write down 9 as next digit of the result. 
Result so far: 1998.610389
The remainder is 47 after subtracting 693 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 13:
77 goes into 470 6 times with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 1998.6103896
If we subtract 462 from 470, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 14:
77 can be fit into 80 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1998.61038961
If we subtract 77 from 80, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 1998.61038961 with a remainder of 3e-09.
