We're dividing 77392949 by 654 
The aim is to understand the frequency of 654 in 77392949.

Let's proceed to step 1:
654 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
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 / 654

Advancing to step 2:
The number 654 fits into 77 0 times, leaving a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Fetch the next digit (3) from the dividend, attach it to 77 and continue: 773 / 654

On to step 3:
773 divided by 654 is 1 with a remainder of 119.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 654 from 773 and we're left with 119.
Append the next digit (9) from the dividend to 119 and continue with: 1199 / 654

Step 4:
654 goes into 1199 1 times with a remainder of 545.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 654 from 1199 to get 545.
Append the next digit (2) from the dividend to 545 and continue with: 5452 / 654

Advancing to step 5:
The number 654 fits into 5452 8 times, leaving a remainder of 220.
The number 8 becomes the next digit in our result. 
Result so far: 118.0
Subtract 5232 from 5452 to get 220.
Take the next digit (9) from the dividend and append it to 220, then repeat: 2209 / 654

Moving on to step 6:
654 goes into 2209 3 times with a remainder of 247.
Record the quotient 3 as the next digit in the result. 
Result so far: 1183.0
Subtract 1962 from 2209 to get 247.
Grab the next digit (4) from the dividend, add it to 247, then carry on: 2474 / 654

Going ahead to step 7:
2474 divided by 654 is 3 with a remainder of 512.
The next digit of our result is 3. 
Result so far: 11833.0
Subtracting 1962 from 2474 leaves us with 512.
Grab the next digit (9) from the dividend, add it to 512, then carry on: 5129 / 654

Going ahead to step 8:
The number 654 fits into 5129 7 times, leaving a remainder of 551.
Write down 7 as next digit of the result. 
Result so far: 118337.0
The remainder is 551 after subtracting 4578 from 5129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

Advancing to step 9:
The number 654 fits into 5510 8 times, leaving a remainder of 278.
The number 8 becomes the next digit in our result. 
Result so far: 118337.8
Subtract 5232 from 5510 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

On to step 10:
2780 divided by 654 is 4 with a remainder of 164.
Put 4 as the next digit of the answer. 
Result so far: 118337.84
If we take 2616 away from 2780, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 11:
654 goes into 1640 2 times with a remainder of 332.
Write down 2 as next digit of the result. 
Result so far: 118337.842
Deduct 1308 from 1640 and we're left with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Moving on to step 12:
654 can be fit into 3320 5 times, resulting in a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 118337.8425
Subtract 3270 from 3320 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 13:
The number 654 fits into 500 0 times, leaving a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 118337.8425
The remainder is 500 after subtracting 0 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Moving on to step 14:
654 can be fit into 5000 7 times, resulting in a remainder of 422.
The number 7 becomes the next digit in our result. 
Result so far: 118337.842507
If we subtract 4578 from 5000, we get 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Going ahead to step 15:
The number 654 fits into 4220 6 times, leaving a remainder of 296.
The number 6 becomes the next digit in our result. 
Result so far: 118337.8425076
Subtracting 3924 from 4220 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 16:
2960 divided by 654 is 4 with a remainder of 344.
Use 4 as the next digit of our solution. 
Result so far: 118337.84250764
Subtracting 2616 from 2960 leaves us with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

The final outcome is 118337.84250764, with a leftover of 3.44e-07.
