77993192 ÷ 140 
The aim is to understand the frequency of 140 in 77993192.

Let's proceed to step 1:
140 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
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 140

Let's proceed to step 2:
140 goes into 77 0 times with 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.
Fetch the next digit (9) from the dividend, attach it to 77 and continue: 779 / 140

Moving on to step 3:
779 divided by 140 is 5 with a remainder of 79.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 700 from 779 and we're left with 79.
Bring next digit (9) of the dividend behind the 79 and repeat the process: 799 / 140

Going ahead to step 4:
If we divide 799 by 140, we get 5 and a remainder of 99.
Put 5 as the next digit of the answer. 
Result so far: 55.0
Subtract 700 from 799 to get 99.
Append the next digit (3) from the dividend to 99 and continue with: 993 / 140

On to step 5:
140 can be fit into 993 7 times, resulting in a remainder of 13.
The next digit of our result is 7. 
Result so far: 557.0
Subtract 980 from 993 to get 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 140

On to step 6:
140 can be fit into 131 0 times, resulting in a remainder of 131.
Put 0 as the next digit of the answer. 
Result so far: 5570.0
Deduct 0 from 131 and we're left with 131.
Take the next digit (9) from the dividend and append it to 131, then repeat: 1319 / 140

Going ahead to step 7:
140 goes into 1319 9 times with a remainder of 59.
Put 9 as the next digit of the answer. 
Result so far: 55709.0
Deduct 1260 from 1319 and we're left with 59.
Grab the next digit (2) from the dividend, add it to 59, then carry on: 592 / 140

Step 8:
140 goes into 592 4 times with a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 557094.0
The remainder is 32 after subtracting 560 from 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
320 divided by 140 is 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 557094.2
If we subtract 280 from 320, we 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 10:
If we divide 400 by 140, we get 2 and a remainder of 120.
Use 2 as the next digit of our solution. 
Result so far: 557094.22
The remainder is 120 after subtracting 280 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

After the division, we end up with 557094.22 and a remainder of 0.12.
