67145585 ÷ 642 
We're looking to find how many times 642 goes into 67145585.

Step 1:
If we divide 6 by 642, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 642

On to step 2:
The number 642 fits into 67 0 times, leaving a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 67 to get 67.
Fetch the next digit (1) from the dividend, attach it to 67 and continue: 671 / 642

On to step 3:
The number 642 fits into 671 1 times, leaving a remainder of 29.
The next digit of our result is 1. 
Result so far: 1.0
If we take 642 away from 671, we end up with 29.
Include the next digit (4) from the dividend after 29, then repeat: 294 / 642

Going ahead to step 4:
294 divided by 642 is 0 with a remainder of 294.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 294 leaves us with 294.
Include the next digit (5) from the dividend after 294, then repeat: 2945 / 642

Let's proceed to step 5:
2945 divided by 642 is 4 with a remainder of 377.
Write down 4 as next digit of the result. 
Result so far: 104.0
Subtracting 2568 from 2945 leaves us with 377.
Grab the next digit (5) from the dividend, add it to 377, then carry on: 3775 / 642

Let's proceed to step 6:
3775 divided by 642 is 5 with a remainder of 565.
Use 5 as the next digit of our solution. 
Result so far: 1045.0
Subtract 3210 from 3775 to get 565.
Bring next digit (8) of the dividend behind the 565 and repeat the process: 5658 / 642

Advancing to step 7:
The number 642 fits into 5658 8 times, leaving a remainder of 522.
Use 8 as the next digit of our solution. 
Result so far: 10458.0
Subtract 5136 from 5658 to get 522.
Include the next digit (5) from the dividend after 522, then repeat: 5225 / 642

Let's proceed to step 8:
If we divide 5225 by 642, we get 8 and a remainder of 89.
Write down 8 as next digit of the result. 
Result so far: 104588.0
If we subtract 5136 from 5225, we get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Moving on to step 9:
When dividing 890 by 642, we get 1 with a remainder of 248.
Write down 1 as next digit of the result. 
Result so far: 104588.1
Subtract 642 from 890 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 10:
642 goes into 2480 3 times with a remainder of 554.
Record the quotient 3 as the next digit in the result. 
Result so far: 104588.13
Subtract 1926 from 2480 to get 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

On to step 11:
642 goes into 5540 8 times with a remainder of 404.
Use 8 as the next digit of our solution. 
Result so far: 104588.138
Deduct 5136 from 5540 and we're left with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Let's proceed to step 12:
The number 642 fits into 4040 6 times, leaving a remainder of 188.
Use 6 as the next digit of our solution. 
Result so far: 104588.1386
Subtract 3852 from 4040 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 13:
1880 divided by 642 is 2 with a remainder of 596.
Use 2 as the next digit of our solution. 
Result so far: 104588.13862
If we take 1284 away from 1880, we end up with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Step 14:
642 can be fit into 5960 9 times, resulting in a remainder of 182.
The number 9 becomes the next digit in our result. 
Result so far: 104588.138629
Subtracting 5778 from 5960 leaves us with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Let's proceed to step 15:
If we divide 1820 by 642, we get 2 and a remainder of 536.
Use 2 as the next digit of our solution. 
Result so far: 104588.1386292
The remainder is 536 after subtracting 1284 from 1820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Step 16:
When dividing 5360 by 642, we get 8 with a remainder of 224.
Put 8 as the next digit of the answer. 
Result so far: 104588.13862928
The remainder is 224 after subtracting 5136 from 5360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Our division results in 104588.13862928 with a remaining 2.24e-07.
