77508390 ÷ 322 
The aim is to understand the frequency of 322 in 77508390.

Moving on to step 1:
7 divided by 322 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 322

Going ahead to step 2:
322 can be fit into 77 0 times, resulting in a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Take the next digit (5) from the dividend and append it to 77, then repeat: 775 / 322

On to step 3:
The number 322 fits into 775 2 times, leaving a remainder of 131.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 644 from 775 to get 131.
Grab the next digit (0) from the dividend, add it to 131, then carry on: 1310 / 322

Step 4:
1310 divided by 322 is 4 with a remainder of 22.
The next digit of our result is 4. 
Result so far: 24.0
Subtracting 1288 from 1310 leaves us with 22.
Fetch the next digit (8) from the dividend, attach it to 22 and continue: 228 / 322

Let's proceed to step 5:
If we divide 228 by 322, we get 0 and a remainder of 228.
Record the quotient 0 as the next digit in the result. 
Result so far: 240.0
Subtract 0 from 228 to get 228.
Grab the next digit (3) from the dividend, add it to 228, then carry on: 2283 / 322

Advancing to step 6:
322 goes into 2283 7 times with a remainder of 29.
The next digit of our result is 7. 
Result so far: 2407.0
If we take 2254 away from 2283, we end up with 29.
Take the next digit (9) from the dividend and append it to 29, then repeat: 299 / 322

Going ahead to step 7:
322 goes into 299 0 times with a remainder of 299.
Use 0 as the next digit of our solution. 
Result so far: 24070.0
Subtracting 0 from 299 leaves us with 299.
Grab the next digit (0) from the dividend, add it to 299, then carry on: 2990 / 322

Step 8:
If we divide 2990 by 322, we get 9 and a remainder of 92.
Use 9 as the next digit of our solution. 
Result so far: 240709.0
The remainder is 92 after subtracting 2898 from 2990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 9:
When dividing 920 by 322, we get 2 with a remainder of 276.
Put 2 as the next digit of the answer. 
Result so far: 240709.2
If we subtract 644 from 920, we get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Advancing to step 10:
2760 divided by 322 is 8 with a remainder of 184.
Use 8 as the next digit of our solution. 
Result so far: 240709.28
If we subtract 2576 from 2760, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 11:
322 goes into 1840 5 times with a remainder of 230.
The next digit of our result is 5. 
Result so far: 240709.285
Subtracting 1610 from 1840 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 12:
322 goes into 2300 7 times with a remainder of 46.
Write down 7 as next digit of the result. 
Result so far: 240709.2857
Subtracting 2254 from 2300 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 13:
When dividing 460 by 322, we get 1 with a remainder of 138.
Use 1 as the next digit of our solution. 
Result so far: 240709.28571
Subtracting 322 from 460 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

On to step 14:
If we divide 1380 by 322, we get 4 and a remainder of 92.
Put 4 as the next digit of the answer. 
Result so far: 240709.285714
If we subtract 1288 from 1380, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 15:
If we divide 920 by 322, we get 2 and a remainder of 276.
Use 2 as the next digit of our solution. 
Result so far: 240709.2857142
Deduct 644 from 920 and we're left with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Advancing to step 16:
The number 322 fits into 2760 8 times, leaving a remainder of 184.
Write down 8 as next digit of the result. 
Result so far: 240709.28571428
Deduct 2576 from 2760 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Our division results in 240709.28571428 with a remaining 1.84e-07.
