We divide 136121 by 77
The aim is to understand the frequency of 77 in 136121.

On to step 1:
77 can be fit into 1 0 times, resulting in 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 (3) from the dividend after 1, then repeat: 13 / 77

Advancing to step 2:
77 can be fit into 13 0 times, resulting in a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 77

On to step 3:
136 divided by 77 is 1 with a remainder of 59.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 77 from 136 leaves us with 59.
Grab the next digit (1) from the dividend, add it to 59, then carry on: 591 / 77

Going ahead to step 4:
The number 77 fits into 591 7 times, leaving a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtracting 539 from 591 leaves us with 52.
Fetch the next digit (2) from the dividend, attach it to 52 and continue: 522 / 77

Step 5:
When dividing 522 by 77, we get 6 with a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 176.0
If we take 462 away from 522, we end up with 60.
Append the next digit (1) from the dividend to 60 and continue with: 601 / 77

Step 6:
When dividing 601 by 77, we get 7 with a remainder of 62.
The number 7 becomes the next digit in our result. 
Result so far: 1767.0
Subtracting 539 from 601 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 7:
77 can be fit into 620 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 1767.8
If we take 616 away from 620, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
The number 77 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 1767.8
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
400 divided by 77 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 1767.805
Subtracting 385 from 400 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
When dividing 150 by 77, we get 1 with a remainder of 73.
Put 1 as the next digit of the answer. 
Result so far: 1767.8051
The remainder is 73 after subtracting 77 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 11:
730 divided by 77 is 9 with a remainder of 37.
The next digit of our result is 9. 
Result so far: 1767.80519
The remainder is 37 after subtracting 693 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 12:
370 divided by 77 is 4 with a remainder of 62.
The number 4 becomes the next digit in our result. 
Result so far: 1767.805194
If we take 308 away from 370, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 13:
When dividing 620 by 77, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 1767.8051948
The remainder is 4 after subtracting 616 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 14:
77 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 1767.8051948
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 1767.8051948 with a remainder of 4e-08.
