66722260 ÷ 642 
Let's see how many times 642 fits into 66722260.

Step 1:
642 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 642

Going ahead to step 2:
The number 642 fits into 66 0 times, leaving a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Include the next digit (7) from the dividend after 66, then repeat: 667 / 642

On to step 3:
The number 642 fits into 667 1 times, leaving a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 642 from 667, we get 25.
Include the next digit (2) from the dividend after 25, then repeat: 252 / 642

Step 4:
642 can be fit into 252 0 times, resulting in a remainder of 252.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 252 to get 252.
Include the next digit (2) from the dividend after 252, then repeat: 2522 / 642

Let's proceed to step 5:
If we divide 2522 by 642, we get 3 and a remainder of 596.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
If we take 1926 away from 2522, we end up with 596.
Fetch the next digit (2) from the dividend, attach it to 596 and continue: 5962 / 642

Going ahead to step 6:
If we divide 5962 by 642, we get 9 and a remainder of 184.
The next digit of our result is 9. 
Result so far: 1039.0
Subtract 5778 from 5962 to get 184.
Fetch the next digit (6) from the dividend, attach it to 184 and continue: 1846 / 642

Advancing to step 7:
When dividing 1846 by 642, we get 2 with a remainder of 562.
Put 2 as the next digit of the answer. 
Result so far: 10392.0
Subtracting 1284 from 1846 leaves us with 562.
Fetch the next digit (0) from the dividend, attach it to 562 and continue: 5620 / 642

Advancing to step 8:
642 goes into 5620 8 times with a remainder of 484.
Put 8 as the next digit of the answer. 
Result so far: 103928.0
Deduct 5136 from 5620 and we're left with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Advancing to step 9:
4840 divided by 642 is 7 with a remainder of 346.
Record the quotient 7 as the next digit in the result. 
Result so far: 103928.7
Subtracting 4494 from 4840 leaves us with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

On to step 10:
The number 642 fits into 3460 5 times, leaving a remainder of 250.
Record the quotient 5 as the next digit in the result. 
Result so far: 103928.75
The remainder is 250 after subtracting 3210 from 3460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 11:
2500 divided by 642 is 3 with a remainder of 574.
Use 3 as the next digit of our solution. 
Result so far: 103928.753
The remainder is 574 after subtracting 1926 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

On to step 12:
5740 divided by 642 is 8 with a remainder of 604.
Put 8 as the next digit of the answer. 
Result so far: 103928.7538
Subtracting 5136 from 5740 leaves us with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Moving on to step 13:
If we divide 6040 by 642, we get 9 and a remainder of 262.
Put 9 as the next digit of the answer. 
Result so far: 103928.75389
Deduct 5778 from 6040 and we're left with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Step 14:
The number 642 fits into 2620 4 times, leaving a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 103928.753894
If we take 2568 away from 2620, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 15:
When dividing 520 by 642, we get 0 with a remainder of 520.
The number 0 becomes the next digit in our result. 
Result so far: 103928.753894
If we subtract 0 from 520, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 16:
The number 642 fits into 5200 8 times, leaving a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 103928.75389408
Deduct 5136 from 5200 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 103928.75389408, and the remainder is 6.4e-08.
