75448750 divided by 642 
Our goal is to divide 75448750 by 642.

Going ahead to step 1:
If we divide 7 by 642, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 642

Moving on to step 2:
642 can be fit into 75 0 times, resulting in a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 75 and we're left with 75.
Append the next digit (4) from the dividend to 75 and continue with: 754 / 642

Step 3:
754 divided by 642 is 1 with a remainder of 112.
The next digit of our result is 1. 
Result so far: 1.0
If we take 642 away from 754, we end up with 112.
Append the next digit (4) from the dividend to 112 and continue with: 1124 / 642

On to step 4:
1124 divided by 642 is 1 with a remainder of 482.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 642 from 1124, we get 482.
Include the next digit (8) from the dividend after 482, then repeat: 4828 / 642

Let's proceed to step 5:
If we divide 4828 by 642, we get 7 and a remainder of 334.
The next digit of our result is 7. 
Result so far: 117.0
Deduct 4494 from 4828 and we're left with 334.
Grab the next digit (7) from the dividend, add it to 334, then carry on: 3347 / 642

Moving on to step 6:
642 can be fit into 3347 5 times, resulting in a remainder of 137.
Use 5 as the next digit of our solution. 
Result so far: 1175.0
Subtract 3210 from 3347 to get 137.
Include the next digit (5) from the dividend after 137, then repeat: 1375 / 642

Step 7:
If we divide 1375 by 642, we get 2 and a remainder of 91.
Write down 2 as next digit of the result. 
Result so far: 11752.0
Subtract 1284 from 1375 to get 91.
Append the next digit (0) from the dividend to 91 and continue with: 910 / 642

Let's proceed to step 8:
When dividing 910 by 642, we get 1 with a remainder of 268.
The number 1 becomes the next digit in our result. 
Result so far: 117521.0
The remainder is 268 after subtracting 642 from 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

On to step 9:
The number 642 fits into 2680 4 times, leaving a remainder of 112.
Put 4 as the next digit of the answer. 
Result so far: 117521.4
Deduct 2568 from 2680 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 10:
1120 divided by 642 is 1 with a remainder of 478.
Use 1 as the next digit of our solution. 
Result so far: 117521.41
The remainder is 478 after subtracting 642 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Going ahead to step 11:
If we divide 4780 by 642, we get 7 and a remainder of 286.
Use 7 as the next digit of our solution. 
Result so far: 117521.417
If we subtract 4494 from 4780, we get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Step 12:
When dividing 2860 by 642, we get 4 with a remainder of 292.
Put 4 as the next digit of the answer. 
Result so far: 117521.4174
If we subtract 2568 from 2860, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Step 13:
642 goes into 2920 4 times with a remainder of 352.
The number 4 becomes the next digit in our result. 
Result so far: 117521.41744
If we subtract 2568 from 2920, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

The final result is 117521.41744 with a remainder of 0.000352.
