84086749 divided by 456 
The aim is to understand the frequency of 456 in 84086749.

Advancing to step 1:
456 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 456

Moving on to step 2:
If we divide 84 by 456, we get 0 and a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Append the next digit (0) from the dividend to 84 and continue with: 840 / 456

On to step 3:
When dividing 840 by 456, we get 1 with a remainder of 384.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 456 from 840 and we're left with 384.
Append the next digit (8) from the dividend to 384 and continue with: 3848 / 456

Let's proceed to step 4:
456 goes into 3848 8 times with a remainder of 200.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtract 3648 from 3848 to get 200.
Append the next digit (6) from the dividend to 200 and continue with: 2006 / 456

Moving on to step 5:
2006 divided by 456 is 4 with a remainder of 182.
The next digit of our result is 4. 
Result so far: 184.0
Subtract 1824 from 2006 to get 182.
Fetch the next digit (7) from the dividend, attach it to 182 and continue: 1827 / 456

Step 6:
When dividing 1827 by 456, we get 4 with a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 1844.0
If we take 1824 away from 1827, we end up with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 456

Step 7:
When dividing 34 by 456, we get 0 with a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 18440.0
Deduct 0 from 34 and we're left with 34.
Fetch the next digit (9) from the dividend, attach it to 34 and continue: 349 / 456

On to step 8:
When dividing 349 by 456, we get 0 with a remainder of 349.
The number 0 becomes the next digit in our result. 
Result so far: 184400.0
If we take 0 away from 349, we end up with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Going ahead to step 9:
When dividing 3490 by 456, we get 7 with a remainder of 298.
The next digit of our result is 7. 
Result so far: 184400.7
Deduct 3192 from 3490 and we're left with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Step 10:
When dividing 2980 by 456, we get 6 with a remainder of 244.
Write down 6 as next digit of the result. 
Result so far: 184400.76
If we subtract 2736 from 2980, we get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Step 11:
456 goes into 2440 5 times with a remainder of 160.
Use 5 as the next digit of our solution. 
Result so far: 184400.765
Subtract 2280 from 2440 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 12:
456 can be fit into 1600 3 times, resulting in a remainder of 232.
The number 3 becomes the next digit in our result. 
Result so far: 184400.7653
Subtract 1368 from 1600 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.

On to step 13:
The number 456 fits into 2320 5 times, leaving a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 184400.76535
The remainder is 40 after subtracting 2280 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 14:
456 can be fit into 400 0 times, resulting in a remainder of 400.
The next digit of our result is 0. 
Result so far: 184400.76535
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 15:
If we divide 4000 by 456, we get 8 and a remainder of 352.
Record the quotient 8 as the next digit in the result. 
Result so far: 184400.7653508
If we subtract 3648 from 4000, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Step 16:
When dividing 3520 by 456, we get 7 with a remainder of 328.
Record the quotient 7 as the next digit in the result. 
Result so far: 184400.76535087
Deduct 3192 from 3520 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Our division results in 184400.76535087 with a remaining 3.28e-07.
