We look at the division of 85963039 by 642 
We're looking to find how many times 642 goes into 85963039.

Moving on to step 1:
642 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 642

On to step 2:
642 can be fit into 85 0 times, resulting in a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Bring next digit (9) of the dividend behind the 85 and repeat the process: 859 / 642

Moving on to step 3:
If we divide 859 by 642, we get 1 and a remainder of 217.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 642 away from 859, we end up with 217.
Fetch the next digit (6) from the dividend, attach it to 217 and continue: 2176 / 642

Step 4:
When dividing 2176 by 642, we get 3 with a remainder of 250.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 250 after subtracting 1926 from 2176.
Bring next digit (3) of the dividend behind the 250 and repeat the process: 2503 / 642

Advancing to step 5:
If we divide 2503 by 642, we get 3 and a remainder of 577.
The number 3 becomes the next digit in our result. 
Result so far: 133.0
Subtracting 1926 from 2503 leaves us with 577.
Take the next digit (0) from the dividend and append it to 577, then repeat: 5770 / 642

Going ahead to step 6:
The number 642 fits into 5770 8 times, leaving a remainder of 634.
Write down 8 as next digit of the result. 
Result so far: 1338.0
Deduct 5136 from 5770 and we're left with 634.
Take the next digit (3) from the dividend and append it to 634, then repeat: 6343 / 642

Step 7:
6343 divided by 642 is 9 with a remainder of 565.
Record the quotient 9 as the next digit in the result. 
Result so far: 13389.0
The remainder is 565 after subtracting 5778 from 6343.
Take the next digit (9) from the dividend and append it to 565, then repeat: 5659 / 642

On to step 8:
The number 642 fits into 5659 8 times, leaving a remainder of 523.
Write down 8 as next digit of the result. 
Result so far: 133898.0
Subtracting 5136 from 5659 leaves us with 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Moving on to step 9:
If we divide 5230 by 642, we get 8 and a remainder of 94.
Write down 8 as next digit of the result. 
Result so far: 133898.8
The remainder is 94 after subtracting 5136 from 5230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 10:
When dividing 940 by 642, we get 1 with a remainder of 298.
Put 1 as the next digit of the answer. 
Result so far: 133898.81
Subtract 642 from 940 to get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Step 11:
642 can be fit into 2980 4 times, resulting in a remainder of 412.
The next digit of our result is 4. 
Result so far: 133898.814
Deduct 2568 from 2980 and we're left with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Let's proceed to step 12:
642 can be fit into 4120 6 times, resulting in a remainder of 268.
The number 6 becomes the next digit in our result. 
Result so far: 133898.8146
Subtracting 3852 from 4120 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Step 13:
If we divide 2680 by 642, we get 4 and a remainder of 112.
Use 4 as the next digit of our solution. 
Result so far: 133898.81464
If we take 2568 away from 2680, we end up 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.

On to step 14:
642 can be fit into 1120 1 times, resulting in a remainder of 478.
Use 1 as the next digit of our solution. 
Result so far: 133898.814641
If we subtract 642 from 1120, we get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

On to step 15:
When dividing 4780 by 642, we get 7 with a remainder of 286.
Write down 7 as next digit of the result. 
Result so far: 133898.8146417
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.

Moving on to step 16:
The number 642 fits into 2860 4 times, leaving a remainder of 292.
The number 4 becomes the next digit in our result. 
Result so far: 133898.81464174
If we take 2568 away from 2860, we end up with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

After the division, we end up with 133898.81464174 and a remainder of 2.92e-07.
