Let's divide 42688423 by 680
We're looking to find how many times 680 goes into 42688423.

Moving on to step 1:
4 divided by 680 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 680

On to step 2:
When dividing 42 by 680, we get 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Grab the next digit (6) from the dividend, add it to 42, then carry on: 426 / 680

On to step 3:
426 divided by 680 is 0 with a remainder of 426.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 426 and we're left with 426.
Bring next digit (8) of the dividend behind the 426 and repeat the process: 4268 / 680

Going ahead to step 4:
680 can be fit into 4268 6 times, resulting in a remainder of 188.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 4080 from 4268 and we're left with 188.
Bring next digit (8) of the dividend behind the 188 and repeat the process: 1888 / 680

On to step 5:
1888 divided by 680 is 2 with a remainder of 528.
Put 2 as the next digit of the answer. 
Result so far: 62.0
Deduct 1360 from 1888 and we're left with 528.
Include the next digit (4) from the dividend after 528, then repeat: 5284 / 680

Moving on to step 6:
5284 divided by 680 is 7 with a remainder of 524.
The number 7 becomes the next digit in our result. 
Result so far: 627.0
Deduct 4760 from 5284 and we're left with 524.
Bring next digit (2) of the dividend behind the 524 and repeat the process: 5242 / 680

Step 7:
The number 680 fits into 5242 7 times, leaving a remainder of 482.
The next digit of our result is 7. 
Result so far: 6277.0
Subtracting 4760 from 5242 leaves us with 482.
Append the next digit (3) from the dividend to 482 and continue with: 4823 / 680

Step 8:
The number 680 fits into 4823 7 times, leaving a remainder of 63.
Use 7 as the next digit of our solution. 
Result so far: 62777.0
The remainder is 63 after subtracting 4760 from 4823.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 9:
If we divide 630 by 680, we get 0 and a remainder of 630.
Use 0 as the next digit of our solution. 
Result so far: 62777.0
Subtracting 0 from 630 leaves us with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Advancing to step 10:
When dividing 6300 by 680, we get 9 with a remainder of 180.
Use 9 as the next digit of our solution. 
Result so far: 62777.09
Subtracting 6120 from 6300 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 11:
680 can be fit into 1800 2 times, resulting in a remainder of 440.
Write down 2 as next digit of the result. 
Result so far: 62777.092
If we take 1360 away from 1800, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 12:
The number 680 fits into 4400 6 times, leaving a remainder of 320.
The number 6 becomes the next digit in our result. 
Result so far: 62777.0926
Subtracting 4080 from 4400 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 13:
The number 680 fits into 3200 4 times, leaving a remainder of 480.
Put 4 as the next digit of the answer. 
Result so far: 62777.09264
If we take 2720 away from 3200, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 14:
4800 divided by 680 is 7 with a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 62777.092647
If we subtract 4760 from 4800, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 15:
400 divided by 680 is 0 with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 62777.092647
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 16:
If we divide 4000 by 680, we get 5 and a remainder of 600.
Record the quotient 5 as the next digit in the result. 
Result so far: 62777.09264705
Subtracting 3400 from 4000 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final outcome is 62777.09264705, with a leftover of 6e-07.
