We look at the division of 86745247 by 552 
The aim is to understand the frequency of 552 in 86745247.

On to step 1:
552 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 552

Step 2:
If we divide 86 by 552, we get 0 and a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Append the next digit (7) from the dividend to 86 and continue with: 867 / 552

On to step 3:
552 can be fit into 867 1 times, resulting in a remainder of 315.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 552 from 867 and we're left with 315.
Grab the next digit (4) from the dividend, add it to 315, then carry on: 3154 / 552

Advancing to step 4:
The number 552 fits into 3154 5 times, leaving a remainder of 394.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 2760 from 3154 and we're left with 394.
Bring next digit (5) of the dividend behind the 394 and repeat the process: 3945 / 552

Let's proceed to step 5:
552 can be fit into 3945 7 times, resulting in a remainder of 81.
Record the quotient 7 as the next digit in the result. 
Result so far: 157.0
Subtracting 3864 from 3945 leaves us with 81.
Include the next digit (2) from the dividend after 81, then repeat: 812 / 552

Let's proceed to step 6:
812 divided by 552 is 1 with a remainder of 260.
Put 1 as the next digit of the answer. 
Result so far: 1571.0
If we subtract 552 from 812, we get 260.
Fetch the next digit (4) from the dividend, attach it to 260 and continue: 2604 / 552

Advancing to step 7:
552 goes into 2604 4 times with a remainder of 396.
The number 4 becomes the next digit in our result. 
Result so far: 15714.0
Deduct 2208 from 2604 and we're left with 396.
Bring next digit (7) of the dividend behind the 396 and repeat the process: 3967 / 552

Let's proceed to step 8:
If we divide 3967 by 552, we get 7 and a remainder of 103.
The number 7 becomes the next digit in our result. 
Result so far: 157147.0
Subtract 3864 from 3967 to get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Advancing to step 9:
The number 552 fits into 1030 1 times, leaving a remainder of 478.
Put 1 as the next digit of the answer. 
Result so far: 157147.1
Deduct 552 from 1030 and we're left with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Let's proceed to step 10:
4780 divided by 552 is 8 with a remainder of 364.
Record the quotient 8 as the next digit in the result. 
Result so far: 157147.18
Subtract 4416 from 4780 to get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Going ahead to step 11:
552 goes into 3640 6 times with a remainder of 328.
Record the quotient 6 as the next digit in the result. 
Result so far: 157147.186
If we subtract 3312 from 3640, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

On to step 12:
The number 552 fits into 3280 5 times, leaving a remainder of 520.
The next digit of our result is 5. 
Result so far: 157147.1865
If we take 2760 away from 3280, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 13:
When dividing 5200 by 552, we get 9 with a remainder of 232.
Put 9 as the next digit of the answer. 
Result so far: 157147.18659
Subtract 4968 from 5200 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Moving on to step 14:
552 can be fit into 2320 4 times, resulting in a remainder of 112.
Write down 4 as next digit of the result. 
Result so far: 157147.186594
The remainder is 112 after subtracting 2208 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 15:
The number 552 fits into 1120 2 times, leaving a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 157147.1865942
Subtract 1104 from 1120 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 16:
160 divided by 552 is 0 with a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 157147.1865942
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final outcome is 157147.1865942, with a leftover of 1.6e-07.
