64164653 ÷ 456 
We want to divide 64164653 by 456.

Step 1:
The number 456 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 456

Going ahead to step 2:
The number 456 fits into 64 0 times, leaving a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Append the next digit (1) from the dividend to 64 and continue with: 641 / 456

Step 3:
When dividing 641 by 456, we get 1 with a remainder of 185.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 456 from 641 and we're left with 185.
Fetch the next digit (6) from the dividend, attach it to 185 and continue: 1856 / 456

Advancing to step 4:
456 goes into 1856 4 times with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 32 after subtracting 1824 from 1856.
Take the next digit (4) from the dividend and append it to 32, then repeat: 324 / 456

Moving on to step 5:
456 can be fit into 324 0 times, resulting in a remainder of 324.
Record the quotient 0 as the next digit in the result. 
Result so far: 140.0
Deduct 0 from 324 and we're left with 324.
Bring next digit (6) of the dividend behind the 324 and repeat the process: 3246 / 456

Going ahead to step 6:
3246 divided by 456 is 7 with a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 1407.0
Subtracting 3192 from 3246 leaves us with 54.
Bring next digit (5) of the dividend behind the 54 and repeat the process: 545 / 456

On to step 7:
545 divided by 456 is 1 with a remainder of 89.
Put 1 as the next digit of the answer. 
Result so far: 14071.0
Subtract 456 from 545 to get 89.
Fetch the next digit (3) from the dividend, attach it to 89 and continue: 893 / 456

Step 8:
When dividing 893 by 456, we get 1 with a remainder of 437.
The next digit of our result is 1. 
Result so far: 140711.0
Deduct 456 from 893 and we're left with 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

On to step 9:
456 goes into 4370 9 times with a remainder of 266.
Put 9 as the next digit of the answer. 
Result so far: 140711.9
Subtracting 4104 from 4370 leaves us with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Going ahead to step 10:
When dividing 2660 by 456, we get 5 with a remainder of 380.
Use 5 as the next digit of our solution. 
Result so far: 140711.95
Subtracting 2280 from 2660 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 11:
456 can be fit into 3800 8 times, resulting in a remainder of 152.
Put 8 as the next digit of the answer. 
Result so far: 140711.958
Subtract 3648 from 3800 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 12:
456 can be fit into 1520 3 times, resulting in a remainder of 152.
Record the quotient 3 as the next digit in the result. 
Result so far: 140711.9583
The remainder is 152 after subtracting 1368 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 13:
If we divide 1520 by 456, we get 3 and a remainder of 152.
The number 3 becomes the next digit in our result. 
Result so far: 140711.95833
If we subtract 1368 from 1520, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

The final result is 140711.95833 with a remainder of 0.000152.
