Let's divide 42579121 by 677
We want to divide 42579121 by 677.

On to step 1:
677 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 677

Moving on to step 2:
677 goes into 42 0 times with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Fetch the next digit (5) from the dividend, attach it to 42 and continue: 425 / 677

Going ahead to step 3:
677 goes into 425 0 times with a remainder of 425.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 425 after subtracting 0 from 425.
Include the next digit (7) from the dividend after 425, then repeat: 4257 / 677

Moving on to step 4:
The number 677 fits into 4257 6 times, leaving a remainder of 195.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 4062 from 4257, we get 195.
Append the next digit (9) from the dividend to 195 and continue with: 1959 / 677

Let's proceed to step 5:
677 can be fit into 1959 2 times, resulting in a remainder of 605.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
If we take 1354 away from 1959, we end up with 605.
Include the next digit (1) from the dividend after 605, then repeat: 6051 / 677

Step 6:
6051 divided by 677 is 8 with a remainder of 635.
The number 8 becomes the next digit in our result. 
Result so far: 628.0
Subtract 5416 from 6051 to get 635.
Bring next digit (2) of the dividend behind the 635 and repeat the process: 6352 / 677

Moving on to step 7:
When dividing 6352 by 677, we get 9 with a remainder of 259.
Put 9 as the next digit of the answer. 
Result so far: 6289.0
Subtract 6093 from 6352 to get 259.
Bring next digit (1) of the dividend behind the 259 and repeat the process: 2591 / 677

Step 8:
If we divide 2591 by 677, we get 3 and a remainder of 560.
Use 3 as the next digit of our solution. 
Result so far: 62893.0
Subtracting 2031 from 2591 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

On to step 9:
677 goes into 5600 8 times with a remainder of 184.
Put 8 as the next digit of the answer. 
Result so far: 62893.8
Subtracting 5416 from 5600 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 10:
677 goes into 1840 2 times with a remainder of 486.
The number 2 becomes the next digit in our result. 
Result so far: 62893.82
If we subtract 1354 from 1840, we get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

On to step 11:
When dividing 4860 by 677, we get 7 with a remainder of 121.
Record the quotient 7 as the next digit in the result. 
Result so far: 62893.827
The remainder is 121 after subtracting 4739 from 4860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Moving on to step 12:
If we divide 1210 by 677, we get 1 and a remainder of 533.
The next digit of our result is 1. 
Result so far: 62893.8271
If we take 677 away from 1210, we end up with 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Let's proceed to step 13:
677 goes into 5330 7 times with a remainder of 591.
The number 7 becomes the next digit in our result. 
Result so far: 62893.82717
Subtracting 4739 from 5330 leaves us with 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

Moving on to step 14:
677 goes into 5910 8 times with a remainder of 494.
Write down 8 as next digit of the result. 
Result so far: 62893.827178
Subtracting 5416 from 5910 leaves us with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

On to step 15:
When dividing 4940 by 677, we get 7 with a remainder of 201.
The number 7 becomes the next digit in our result. 
Result so far: 62893.8271787
Subtracting 4739 from 4940 leaves us with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Let's proceed to step 16:
2010 divided by 677 is 2 with a remainder of 656.
The number 2 becomes the next digit in our result. 
Result so far: 62893.82717872
Subtract 1354 from 2010 to get 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

The final outcome is 62893.82717872, with a leftover of 6.56e-07.
