74753612 ÷ 642 
We want to figure out the number of times 74753612 can be divided by 642.

Advancing to step 1:
642 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 642

Moving on to step 2:
If we divide 74 by 642, we get 0 and a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Bring next digit (7) of the dividend behind the 74 and repeat the process: 747 / 642

Let's proceed to step 3:
642 can be fit into 747 1 times, resulting in a remainder of 105.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 105 after subtracting 642 from 747.
Fetch the next digit (5) from the dividend, attach it to 105 and continue: 1055 / 642

Going ahead to step 4:
1055 divided by 642 is 1 with a remainder of 413.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 642 away from 1055, we end up with 413.
Append the next digit (3) from the dividend to 413 and continue with: 4133 / 642

Going ahead to step 5:
If we divide 4133 by 642, we get 6 and a remainder of 281.
Use 6 as the next digit of our solution. 
Result so far: 116.0
Deduct 3852 from 4133 and we're left with 281.
Fetch the next digit (6) from the dividend, attach it to 281 and continue: 2816 / 642

Step 6:
If we divide 2816 by 642, we get 4 and a remainder of 248.
Record the quotient 4 as the next digit in the result. 
Result so far: 1164.0
If we take 2568 away from 2816, we end up with 248.
Take the next digit (1) from the dividend and append it to 248, then repeat: 2481 / 642

Step 7:
2481 divided by 642 is 3 with a remainder of 555.
The number 3 becomes the next digit in our result. 
Result so far: 11643.0
The remainder is 555 after subtracting 1926 from 2481.
Append the next digit (2) from the dividend to 555 and continue with: 5552 / 642

Moving on to step 8:
When dividing 5552 by 642, we get 8 with a remainder of 416.
Use 8 as the next digit of our solution. 
Result so far: 116438.0
Subtract 5136 from 5552 to get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 9:
When dividing 4160 by 642, we get 6 with a remainder of 308.
Record the quotient 6 as the next digit in the result. 
Result so far: 116438.6
If we take 3852 away from 4160, we end up with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 10:
642 goes into 3080 4 times with a remainder of 512.
The next digit of our result is 4. 
Result so far: 116438.64
Deduct 2568 from 3080 and we're left with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Moving on to step 11:
The number 642 fits into 5120 7 times, leaving a remainder of 626.
The next digit of our result is 7. 
Result so far: 116438.647
Deduct 4494 from 5120 and we're left 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.

Moving on to step 12:
6260 divided by 642 is 9 with a remainder of 482.
Write down 9 as next digit of the result. 
Result so far: 116438.6479
If we take 5778 away from 6260, we end up with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Let's proceed to step 13:
If we divide 4820 by 642, we get 7 and a remainder of 326.
Write down 7 as next digit of the result. 
Result so far: 116438.64797
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.

Going ahead to step 14:
642 can be fit into 3260 5 times, resulting in a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 116438.647975
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.

On to step 15:
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: 116438.647975
Deduct 0 from 500 and we're left with 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 16:
The number 642 fits into 5000 7 times, leaving a remainder of 506.
Write down 7 as next digit of the result. 
Result so far: 116438.64797507
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.

The final outcome is 116438.64797507, with a leftover of 5.06e-07.
