75351592 ÷ 642 
Our goal is to divide 75351592 by 642.

On to step 1:
642 goes into 7 0 times with 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.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 642

Going ahead to step 2:
642 goes into 75 0 times with a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Take the next digit (3) from the dividend and append it to 75, then repeat: 753 / 642

Moving on to step 3:
642 can be fit into 753 1 times, resulting in a remainder of 111.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 642 from 753 to get 111.
Fetch the next digit (5) from the dividend, attach it to 111 and continue: 1115 / 642

Let's proceed to step 4:
When dividing 1115 by 642, we get 1 with a remainder of 473.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 642 from 1115 to get 473.
Grab the next digit (1) from the dividend, add it to 473, then carry on: 4731 / 642

Let's proceed to step 5:
642 can be fit into 4731 7 times, resulting in a remainder of 237.
Put 7 as the next digit of the answer. 
Result so far: 117.0
If we subtract 4494 from 4731, we get 237.
Append the next digit (5) from the dividend to 237 and continue with: 2375 / 642

On to step 6:
642 goes into 2375 3 times with a remainder of 449.
The number 3 becomes the next digit in our result. 
Result so far: 1173.0
Subtract 1926 from 2375 to get 449.
Fetch the next digit (9) from the dividend, attach it to 449 and continue: 4499 / 642

Step 7:
When dividing 4499 by 642, we get 7 with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 11737.0
Subtract 4494 from 4499 to get 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 642

Moving on to step 8:
If we divide 52 by 642, we get 0 and a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 117370.0
The remainder is 52 after subtracting 0 from 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 9:
520 divided by 642 is 0 with a remainder of 520.
Use 0 as the next digit of our solution. 
Result so far: 117370.0
If we take 0 away from 520, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 10:
If we divide 5200 by 642, we get 8 and a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 117370.08
If we subtract 5136 from 5200, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 11:
642 can be fit into 640 0 times, resulting in a remainder of 640.
Put 0 as the next digit of the answer. 
Result so far: 117370.08
If we subtract 0 from 640, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 12:
When dividing 6400 by 642, we get 9 with a remainder of 622.
The number 9 becomes the next digit in our result. 
Result so far: 117370.0809
Subtract 5778 from 6400 to get 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Advancing to step 13:
If we divide 6220 by 642, we get 9 and a remainder of 442.
The number 9 becomes the next digit in our result. 
Result so far: 117370.08099
Subtract 5778 from 6220 to get 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

After the division, we end up with 117370.08099 and a remainder of 0.000442.
