643914 divided by 68 
Our goal is to divide 643914 by 68.

Let's proceed to step 1:
The number 68 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 68

Advancing to step 2:
When dividing 64 by 68, we get 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Include the next digit (3) from the dividend after 64, then repeat: 643 / 68

Let's proceed to step 3:
When dividing 643 by 68, we get 9 with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 612 from 643 leaves us with 31.
Grab the next digit (9) from the dividend, add it to 31, then carry on: 319 / 68

Moving on to step 4:
68 goes into 319 4 times with a remainder of 47.
Write down 4 as next digit of the result. 
Result so far: 94.0
If we take 272 away from 319, we end up with 47.
Bring next digit (1) of the dividend behind the 47 and repeat the process: 471 / 68

Moving on to step 5:
When dividing 471 by 68, we get 6 with a remainder of 63.
Write down 6 as next digit of the result. 
Result so far: 946.0
If we subtract 408 from 471, we get 63.
Fetch the next digit (4) from the dividend, attach it to 63 and continue: 634 / 68

Moving on to step 6:
634 divided by 68 is 9 with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 9469.0
Subtract 612 from 634 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
68 can be fit into 220 3 times, resulting in a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 9469.3
Subtracting 204 from 220 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
The number 68 fits into 160 2 times, leaving a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 9469.32
Subtract 136 from 160 to 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.

On to step 9:
If we divide 240 by 68, we get 3 and a remainder of 36.
Use 3 as the next digit of our solution. 
Result so far: 9469.323
Subtracting 204 from 240 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 10:
68 can be fit into 360 5 times, resulting in a remainder of 20.
The next digit of our result is 5. 
Result so far: 9469.3235
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.

Going ahead to step 11:
200 divided by 68 is 2 with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 9469.32352
The remainder is 64 after subtracting 136 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 12:
The number 68 fits into 640 9 times, leaving a remainder of 28.
Record the quotient 9 as the next digit in the result. 
Result so far: 9469.323529
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.

Step 13:
68 can be fit into 280 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 9469.3235294
The remainder is 8 after subtracting 272 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 14:
68 can be fit into 80 1 times, resulting in a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 9469.32352941
If we subtract 68 from 80, we 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.

The final outcome is 9469.32352941, with a leftover of 1.2e-08.
