Let's divide 251137 by 77
The aim is to understand the frequency of 77 in 251137.

On to step 1:
77 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 77

On to step 2:
When dividing 25 by 77, we get 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Take the next digit (1) from the dividend and append it to 25, then repeat: 251 / 77

On to step 3:
If we divide 251 by 77, we get 3 and a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 231 from 251 and we're left with 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 77

Step 4:
77 can be fit into 201 2 times, resulting in a remainder of 47.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
If we subtract 154 from 201, we get 47.
Take the next digit (3) from the dividend and append it to 47, then repeat: 473 / 77

Advancing to step 5:
The number 77 fits into 473 6 times, leaving a remainder of 11.
The next digit of our result is 6. 
Result so far: 326.0
If we take 462 away from 473, we end up with 11.
Include the next digit (7) from the dividend after 11, then repeat: 117 / 77

Let's proceed to step 6:
If we divide 117 by 77, we get 1 and a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 3261.0
Subtract 77 from 117 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.

Advancing to step 7:
The number 77 fits into 400 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 3261.5
Deduct 385 from 400 and we're left 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 8:
When dividing 150 by 77, we get 1 with a remainder of 73.
The next digit of our result is 1. 
Result so far: 3261.51
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.

Going ahead to step 9:
If we divide 730 by 77, we get 9 and a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 3261.519
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.

Moving on to step 10:
The number 77 fits into 370 4 times, leaving a remainder of 62.
The number 4 becomes the next digit in our result. 
Result so far: 3261.5194
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.

Moving on to step 11:
77 can be fit into 620 8 times, resulting in a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 3261.51948
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.

Moving on to step 12:
When dividing 40 by 77, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 3261.51948
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 13:
The number 77 fits into 400 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 3261.5194805
The remainder is 15 after subtracting 385 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 14:
The number 77 fits into 150 1 times, leaving a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 3261.51948051
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.

In conclusion, the division gives 3261.51948051 with a balance of 7.3e-08.
