72548962 ÷ 646 
Let's see how many times 646 fits into 72548962.

Moving on to step 1:
7 divided by 646 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 646

Advancing to step 2:
The number 646 fits into 72 0 times, leaving a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Grab the next digit (5) from the dividend, add it to 72, then carry on: 725 / 646

Going ahead to step 3:
If we divide 725 by 646, we get 1 and a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 79 after subtracting 646 from 725.
Append the next digit (4) from the dividend to 79 and continue with: 794 / 646

Let's proceed to step 4:
When dividing 794 by 646, we get 1 with a remainder of 148.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 646 from 794 and we're left with 148.
Append the next digit (8) from the dividend to 148 and continue with: 1488 / 646

Let's proceed to step 5:
The number 646 fits into 1488 2 times, leaving a remainder of 196.
Put 2 as the next digit of the answer. 
Result so far: 112.0
Subtract 1292 from 1488 to get 196.
Include the next digit (9) from the dividend after 196, then repeat: 1969 / 646

Going ahead to step 6:
1969 divided by 646 is 3 with a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 1123.0
The remainder is 31 after subtracting 1938 from 1969.
Fetch the next digit (6) from the dividend, attach it to 31 and continue: 316 / 646

Going ahead to step 7:
646 can be fit into 316 0 times, resulting in a remainder of 316.
Record the quotient 0 as the next digit in the result. 
Result so far: 11230.0
Subtracting 0 from 316 leaves us with 316.
Include the next digit (2) from the dividend after 316, then repeat: 3162 / 646

Step 8:
If we divide 3162 by 646, we get 4 and a remainder of 578.
The number 4 becomes the next digit in our result. 
Result so far: 112304.0
If we subtract 2584 from 3162, we get 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

On to step 9:
The number 646 fits into 5780 8 times, leaving a remainder of 612.
Use 8 as the next digit of our solution. 
Result so far: 112304.8
Subtract 5168 from 5780 to get 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

On to step 10:
646 goes into 6120 9 times with a remainder of 306.
Put 9 as the next digit of the answer. 
Result so far: 112304.89
Deduct 5814 from 6120 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Going ahead to step 11:
The number 646 fits into 3060 4 times, leaving a remainder of 476.
The number 4 becomes the next digit in our result. 
Result so far: 112304.894
The remainder is 476 after subtracting 2584 from 3060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Let's proceed to step 12:
4760 divided by 646 is 7 with a remainder of 238.
Put 7 as the next digit of the answer. 
Result so far: 112304.8947
If we take 4522 away from 4760, we end up with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 13:
2380 divided by 646 is 3 with a remainder of 442.
The number 3 becomes the next digit in our result. 
Result so far: 112304.89473
Deduct 1938 from 2380 and we're left with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

On to step 14:
646 goes into 4420 6 times with a remainder of 544.
The number 6 becomes the next digit in our result. 
Result so far: 112304.894736
The remainder is 544 after subtracting 3876 from 4420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

On to step 15:
If we divide 5440 by 646, we get 8 and a remainder of 272.
Use 8 as the next digit of our solution. 
Result so far: 112304.8947368
Subtracting 5168 from 5440 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

On to step 16:
646 goes into 2720 4 times with a remainder of 136.
Put 4 as the next digit of the answer. 
Result so far: 112304.89473684
If we take 2584 away from 2720, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

The final outcome is 112304.89473684, with a leftover of 1.36e-07.
