We're dividing 77210778 by 149 
The aim is to understand the frequency of 149 in 77210778.

Moving on to step 1:
149 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 149

Moving on to step 2:
149 goes into 77 0 times with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Include the next digit (2) from the dividend after 77, then repeat: 772 / 149

Advancing to step 3:
772 divided by 149 is 5 with a remainder of 27.
The next digit of our result is 5. 
Result so far: 5.0
If we take 745 away from 772, we end up with 27.
Append the next digit (1) from the dividend to 27 and continue with: 271 / 149

Moving on to step 4:
When dividing 271 by 149, we get 1 with a remainder of 122.
The next digit of our result is 1. 
Result so far: 51.0
Deduct 149 from 271 and we're left with 122.
Include the next digit (0) from the dividend after 122, then repeat: 1220 / 149

Let's proceed to step 5:
149 can be fit into 1220 8 times, resulting in a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 518.0
Subtracting 1192 from 1220 leaves us with 28.
Bring next digit (7) of the dividend behind the 28 and repeat the process: 287 / 149

Let's proceed to step 6:
When dividing 287 by 149, we get 1 with a remainder of 138.
The number 1 becomes the next digit in our result. 
Result so far: 5181.0
The remainder is 138 after subtracting 149 from 287.
Bring next digit (7) of the dividend behind the 138 and repeat the process: 1387 / 149

On to step 7:
1387 divided by 149 is 9 with a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 51819.0
Subtracting 1341 from 1387 leaves us with 46.
Grab the next digit (8) from the dividend, add it to 46, then carry on: 468 / 149

Step 8:
The number 149 fits into 468 3 times, leaving a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 518193.0
Subtract 447 from 468 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 9:
When dividing 210 by 149, we get 1 with a remainder of 61.
The next digit of our result is 1. 
Result so far: 518193.1
Deduct 149 from 210 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 10:
149 goes into 610 4 times with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 518193.14
Subtracting 596 from 610 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 11:
140 divided by 149 is 0 with a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 518193.14
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 12:
149 goes into 1400 9 times with a remainder of 59.
Put 9 as the next digit of the answer. 
Result so far: 518193.1409
Deduct 1341 from 1400 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 13:
When dividing 590 by 149, we get 3 with a remainder of 143.
The next digit of our result is 3. 
Result so far: 518193.14093
Deduct 447 from 590 and we're left with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Let's proceed to step 14:
When dividing 1430 by 149, we get 9 with a remainder of 89.
The number 9 becomes the next digit in our result. 
Result so far: 518193.140939
If we take 1341 away from 1430, we end up with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Moving on to step 15:
149 can be fit into 890 5 times, resulting in a remainder of 145.
The next digit of our result is 5. 
Result so far: 518193.1409395
The remainder is 145 after subtracting 745 from 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Step 16:
149 can be fit into 1450 9 times, resulting in a remainder of 109.
Record the quotient 9 as the next digit in the result. 
Result so far: 518193.14093959
If we subtract 1341 from 1450, we get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

After the division, we end up with 518193.14093959 and a remainder of 1.09e-07.
