We divide 51108240 by 171
The aim is to understand the frequency of 171 in 51108240.

On to step 1:
When dividing 5 by 171, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 171

Let's proceed to step 2:
When dividing 51 by 171, we get 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Append the next digit (1) from the dividend to 51 and continue with: 511 / 171

Moving on to step 3:
171 can be fit into 511 2 times, resulting in a remainder of 169.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 342 away from 511, we end up with 169.
Bring next digit (0) of the dividend behind the 169 and repeat the process: 1690 / 171

Going ahead to step 4:
171 can be fit into 1690 9 times, resulting in a remainder of 151.
Put 9 as the next digit of the answer. 
Result so far: 29.0
If we subtract 1539 from 1690, we get 151.
Bring next digit (8) of the dividend behind the 151 and repeat the process: 1518 / 171

On to step 5:
When dividing 1518 by 171, we get 8 with a remainder of 150.
The next digit of our result is 8. 
Result so far: 298.0
If we take 1368 away from 1518, we end up with 150.
Take the next digit (2) from the dividend and append it to 150, then repeat: 1502 / 171

On to step 6:
1502 divided by 171 is 8 with a remainder of 134.
The number 8 becomes the next digit in our result. 
Result so far: 2988.0
Subtracting 1368 from 1502 leaves us with 134.
Grab the next digit (4) from the dividend, add it to 134, then carry on: 1344 / 171

Step 7:
1344 divided by 171 is 7 with a remainder of 147.
The next digit of our result is 7. 
Result so far: 29887.0
Subtracting 1197 from 1344 leaves us with 147.
Take the next digit (0) from the dividend and append it to 147, then repeat: 1470 / 171

Going ahead to step 8:
When dividing 1470 by 171, we get 8 with a remainder of 102.
The number 8 becomes the next digit in our result. 
Result so far: 298878.0
Subtracting 1368 from 1470 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Moving on to step 9:
1020 divided by 171 is 5 with a remainder of 165.
The number 5 becomes the next digit in our result. 
Result so far: 298878.5
Subtracting 855 from 1020 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Let's proceed to step 10:
If we divide 1650 by 171, we get 9 and a remainder of 111.
The number 9 becomes the next digit in our result. 
Result so far: 298878.59
If we subtract 1539 from 1650, we get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Going ahead to step 11:
If we divide 1110 by 171, we get 6 and a remainder of 84.
Record the quotient 6 as the next digit in the result. 
Result so far: 298878.596
Subtract 1026 from 1110 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 12:
When dividing 840 by 171, we get 4 with a remainder of 156.
The number 4 becomes the next digit in our result. 
Result so far: 298878.5964
Subtracting 684 from 840 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 13:
The number 171 fits into 1560 9 times, leaving a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 298878.59649
The remainder is 21 after subtracting 1539 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 14:
171 goes into 210 1 times with a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 298878.596491
Deduct 171 from 210 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 15:
171 can be fit into 390 2 times, resulting in a remainder of 48.
The next digit of our result is 2. 
Result so far: 298878.5964912
If we subtract 342 from 390, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 16:
If we divide 480 by 171, we get 2 and a remainder of 138.
Use 2 as the next digit of our solution. 
Result so far: 298878.59649122
The remainder is 138 after subtracting 342 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

The final outcome is 298878.59649122, with a leftover of 1.38e-07.
