We're dividing 77556212 by 149 
The aim is to understand the frequency of 149 in 77556212.

Step 1:
The number 149 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 149

On to step 2:
149 can be fit into 77 0 times, resulting in a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Take the next digit (5) from the dividend and append it to 77, then repeat: 775 / 149

Let's proceed to step 3:
149 can be fit into 775 5 times, resulting in a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 745 from 775 and we're left with 30.
Fetch the next digit (5) from the dividend, attach it to 30 and continue: 305 / 149

Advancing to step 4:
The number 149 fits into 305 2 times, leaving a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 52.0
Deduct 298 from 305 and we're left with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 149

On to step 5:
149 goes into 76 0 times with a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 520.0
Deduct 0 from 76 and we're left with 76.
Bring next digit (2) of the dividend behind the 76 and repeat the process: 762 / 149

On to step 6:
149 can be fit into 762 5 times, resulting in a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 5205.0
Subtracting 745 from 762 leaves us with 17.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 149

Advancing to step 7:
If we divide 171 by 149, we get 1 and a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 52051.0
Subtracting 149 from 171 leaves us with 22.
Fetch the next digit (2) from the dividend, attach it to 22 and continue: 222 / 149

On to step 8:
When dividing 222 by 149, we get 1 with a remainder of 73.
Put 1 as the next digit of the answer. 
Result so far: 520511.0
The remainder is 73 after subtracting 149 from 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 9:
149 can be fit into 730 4 times, resulting in a remainder of 134.
The number 4 becomes the next digit in our result. 
Result so far: 520511.4
Deduct 596 from 730 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Moving on to step 10:
The number 149 fits into 1340 8 times, leaving a remainder of 148.
Put 8 as the next digit of the answer. 
Result so far: 520511.48
Subtracting 1192 from 1340 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 11:
1480 divided by 149 is 9 with a remainder of 139.
Put 9 as the next digit of the answer. 
Result so far: 520511.489
Subtract 1341 from 1480 to get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

On to step 12:
149 can be fit into 1390 9 times, resulting in a remainder of 49.
Write down 9 as next digit of the result. 
Result so far: 520511.4899
The remainder is 49 after subtracting 1341 from 1390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The final outcome is 520511.4899, with a leftover of 0.00049.
