80051617 ÷ 392 
The aim is to understand the frequency of 392 in 80051617.

Advancing to step 1:
8 divided by 392 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 392

Moving on to step 2:
If we divide 80 by 392, we get 0 and a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Include the next digit (0) from the dividend after 80, then repeat: 800 / 392

Advancing to step 3:
The number 392 fits into 800 2 times, leaving a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 784 from 800 and we're left with 16.
Include the next digit (5) from the dividend after 16, then repeat: 165 / 392

Let's proceed to step 4:
When dividing 165 by 392, we get 0 with a remainder of 165.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtracting 0 from 165 leaves us with 165.
Grab the next digit (1) from the dividend, add it to 165, then carry on: 1651 / 392

Let's proceed to step 5:
If we divide 1651 by 392, we get 4 and a remainder of 83.
Record the quotient 4 as the next digit in the result. 
Result so far: 204.0
Subtract 1568 from 1651 to get 83.
Append the next digit (6) from the dividend to 83 and continue with: 836 / 392

On to step 6:
392 can be fit into 836 2 times, resulting in a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 2042.0
If we subtract 784 from 836, we get 52.
Fetch the next digit (1) from the dividend, attach it to 52 and continue: 521 / 392

Going ahead to step 7:
The number 392 fits into 521 1 times, leaving a remainder of 129.
The number 1 becomes the next digit in our result. 
Result so far: 20421.0
Subtracting 392 from 521 leaves us with 129.
Bring next digit (7) of the dividend behind the 129 and repeat the process: 1297 / 392

Moving on to step 8:
392 can be fit into 1297 3 times, resulting in a remainder of 121.
Put 3 as the next digit of the answer. 
Result so far: 204213.0
Subtracting 1176 from 1297 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Advancing to step 9:
392 can be fit into 1210 3 times, resulting in a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 204213.3
Deduct 1176 from 1210 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 10:
If we divide 340 by 392, we get 0 and a remainder of 340.
The number 0 becomes the next digit in our result. 
Result so far: 204213.3
If we take 0 away from 340, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 11:
When dividing 3400 by 392, we get 8 with a remainder of 264.
Put 8 as the next digit of the answer. 
Result so far: 204213.308
If we take 3136 away from 3400, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Step 12:
If we divide 2640 by 392, we get 6 and a remainder of 288.
Use 6 as the next digit of our solution. 
Result so far: 204213.3086
Subtracting 2352 from 2640 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 13:
The number 392 fits into 2880 7 times, leaving a remainder of 136.
Record the quotient 7 as the next digit in the result. 
Result so far: 204213.30867
Subtracting 2744 from 2880 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 14:
1360 divided by 392 is 3 with a remainder of 184.
Use 3 as the next digit of our solution. 
Result so far: 204213.308673
Subtracting 1176 from 1360 leaves us 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.

On to step 15:
392 goes into 1840 4 times with a remainder of 272.
Write down 4 as next digit of the result. 
Result so far: 204213.3086734
Subtracting 1568 from 1840 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Step 16:
392 goes into 2720 6 times with a remainder of 368.
Record the quotient 6 as the next digit in the result. 
Result so far: 204213.30867346
The remainder is 368 after subtracting 2352 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Our division results in 204213.30867346 with a remaining 3.68e-07.
