642990 divided by 68 
We want to divide 642990 by 68.

On to step 1:
The number 68 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 68

Going ahead to step 2:
If we divide 64 by 68, we get 0 and a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Take the next digit (2) from the dividend and append it to 64, then repeat: 642 / 68

Let's proceed to step 3:
642 divided by 68 is 9 with a remainder of 30.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 612 from 642 leaves us with 30.
Append the next digit (9) from the dividend to 30 and continue with: 309 / 68

Moving on to step 4:
68 goes into 309 4 times with a remainder of 37.
Put 4 as the next digit of the answer. 
Result so far: 94.0
Deduct 272 from 309 and we're left with 37.
Append the next digit (9) from the dividend to 37 and continue with: 379 / 68

On to step 5:
The number 68 fits into 379 5 times, leaving a remainder of 39.
Record the quotient 5 as the next digit in the result. 
Result so far: 945.0
Deduct 340 from 379 and we're left with 39.
Bring next digit (0) of the dividend behind the 39 and repeat the process: 390 / 68

Let's proceed to step 6:
390 divided by 68 is 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 9455.0
Subtracting 340 from 390 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 7:
68 can be fit into 500 7 times, resulting in a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 9455.7
If we subtract 476 from 500, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 8:
If we divide 240 by 68, we get 3 and a remainder of 36.
Record the quotient 3 as the next digit in the result. 
Result so far: 9455.73
If we subtract 204 from 240, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
If we divide 360 by 68, we get 5 and a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 9455.735
If we take 340 away from 360, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
If we divide 200 by 68, we get 2 and a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 9455.7352
Subtract 136 from 200 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 11:
When dividing 640 by 68, we get 9 with a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 9455.73529
Subtract 612 from 640 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 12:
If we divide 280 by 68, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 9455.735294
Deduct 272 from 280 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
The number 68 fits into 80 1 times, leaving a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 9455.7352941
Subtract 68 from 80 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 14:
If we divide 120 by 68, we get 1 and a remainder of 52.
Put 1 as the next digit of the answer. 
Result so far: 9455.73529411
If we subtract 68 from 120, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Our division results in 9455.73529411 with a remaining 5.2e-08.
