We divide 64857886 by 123
We're looking to find how many times 123 goes into 64857886.

Advancing to step 1:
123 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 123

On to step 2:
123 can be fit into 64 0 times, resulting in a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Grab the next digit (8) from the dividend, add it to 64, then carry on: 648 / 123

On to step 3:
648 divided by 123 is 5 with a remainder of 33.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 33 after subtracting 615 from 648.
Fetch the next digit (5) from the dividend, attach it to 33 and continue: 335 / 123

Let's proceed to step 4:
123 can be fit into 335 2 times, resulting in a remainder of 89.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
If we subtract 246 from 335, we get 89.
Include the next digit (7) from the dividend after 89, then repeat: 897 / 123

Step 5:
The number 123 fits into 897 7 times, leaving a remainder of 36.
Write down 7 as next digit of the result. 
Result so far: 527.0
Subtracting 861 from 897 leaves us with 36.
Take the next digit (8) from the dividend and append it to 36, then repeat: 368 / 123

On to step 6:
368 divided by 123 is 2 with a remainder of 122.
Put 2 as the next digit of the answer. 
Result so far: 5272.0
If we take 246 away from 368, we end up with 122.
Fetch the next digit (8) from the dividend, attach it to 122 and continue: 1228 / 123

Let's proceed to step 7:
The number 123 fits into 1228 9 times, leaving a remainder of 121.
Put 9 as the next digit of the answer. 
Result so far: 52729.0
The remainder is 121 after subtracting 1107 from 1228.
Grab the next digit (6) from the dividend, add it to 121, then carry on: 1216 / 123

Advancing to step 8:
If we divide 1216 by 123, we get 9 and a remainder of 109.
The number 9 becomes the next digit in our result. 
Result so far: 527299.0
If we subtract 1107 from 1216, we get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Step 9:
When dividing 1090 by 123, we get 8 with a remainder of 106.
The next digit of our result is 8. 
Result so far: 527299.8
The remainder is 106 after subtracting 984 from 1090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 10:
If we divide 1060 by 123, we get 8 and a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 527299.88
Deduct 984 from 1060 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Our division results in 527299.88 with a remaining 0.076.
