79775753 ÷ 642 
Let's see how many times 642 fits into 79775753.

Advancing to step 1:
If we divide 7 by 642, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 642

On to step 2:
642 can be fit into 79 0 times, resulting in a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Append the next digit (7) from the dividend to 79 and continue with: 797 / 642

On to step 3:
When dividing 797 by 642, we get 1 with a remainder of 155.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 642 from 797, we get 155.
Fetch the next digit (7) from the dividend, attach it to 155 and continue: 1557 / 642

On to step 4:
642 goes into 1557 2 times with a remainder of 273.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 273 after subtracting 1284 from 1557.
Include the next digit (5) from the dividend after 273, then repeat: 2735 / 642

Step 5:
If we divide 2735 by 642, we get 4 and a remainder of 167.
Record the quotient 4 as the next digit in the result. 
Result so far: 124.0
Subtract 2568 from 2735 to get 167.
Grab the next digit (7) from the dividend, add it to 167, then carry on: 1677 / 642

Going ahead to step 6:
If we divide 1677 by 642, we get 2 and a remainder of 393.
The number 2 becomes the next digit in our result. 
Result so far: 1242.0
Subtracting 1284 from 1677 leaves us with 393.
Bring next digit (5) of the dividend behind the 393 and repeat the process: 3935 / 642

Step 7:
When dividing 3935 by 642, we get 6 with a remainder of 83.
The number 6 becomes the next digit in our result. 
Result so far: 12426.0
Subtract 3852 from 3935 to get 83.
Take the next digit (3) from the dividend and append it to 83, then repeat: 833 / 642

Advancing to step 8:
642 can be fit into 833 1 times, resulting in a remainder of 191.
Write down 1 as next digit of the result. 
Result so far: 124261.0
If we take 642 away from 833, we end up with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Step 9:
The number 642 fits into 1910 2 times, leaving a remainder of 626.
The number 2 becomes the next digit in our result. 
Result so far: 124261.2
If we take 1284 away from 1910, we end up with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Let's proceed to step 10:
The number 642 fits into 6260 9 times, leaving a remainder of 482.
Use 9 as the next digit of our solution. 
Result so far: 124261.29
The remainder is 482 after subtracting 5778 from 6260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

On to step 11:
If we divide 4820 by 642, we get 7 and a remainder of 326.
Put 7 as the next digit of the answer. 
Result so far: 124261.297
Subtract 4494 from 4820 to get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

On to step 12:
642 goes into 3260 5 times with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 124261.2975
Deduct 3210 from 3260 and we're left 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.

Advancing to step 13:
642 can be fit into 500 0 times, resulting in a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 124261.2975
The remainder is 500 after subtracting 0 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 14:
The number 642 fits into 5000 7 times, leaving a remainder of 506.
The next digit of our result is 7. 
Result so far: 124261.297507
The remainder is 506 after subtracting 4494 from 5000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Step 15:
The number 642 fits into 5060 7 times, leaving a remainder of 566.
The next digit of our result is 7. 
Result so far: 124261.2975077
Subtracting 4494 from 5060 leaves us with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

The quotient of the division is 124261.2975077, and the remainder is 5.66e-06.
