Let's divide 87064793 by 642
We want to figure out the number of times 87064793 can be divided by 642.

Let's proceed to step 1:
642 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 642

Let's proceed to step 2:
642 goes into 87 0 times with a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Append the next digit (0) from the dividend to 87 and continue with: 870 / 642

Advancing to step 3:
642 can be fit into 870 1 times, resulting in a remainder of 228.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 642 from 870, we get 228.
Bring next digit (6) of the dividend behind the 228 and repeat the process: 2286 / 642

Going ahead to step 4:
When dividing 2286 by 642, we get 3 with a remainder of 360.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 1926 away from 2286, we end up with 360.
Take the next digit (4) from the dividend and append it to 360, then repeat: 3604 / 642

Let's proceed to step 5:
642 can be fit into 3604 5 times, resulting in a remainder of 394.
Use 5 as the next digit of our solution. 
Result so far: 135.0
Subtract 3210 from 3604 to get 394.
Take the next digit (7) from the dividend and append it to 394, then repeat: 3947 / 642

On to step 6:
642 goes into 3947 6 times with a remainder of 95.
The next digit of our result is 6. 
Result so far: 1356.0
The remainder is 95 after subtracting 3852 from 3947.
Fetch the next digit (9) from the dividend, attach it to 95 and continue: 959 / 642

Advancing to step 7:
When dividing 959 by 642, we get 1 with a remainder of 317.
Use 1 as the next digit of our solution. 
Result so far: 13561.0
Subtracting 642 from 959 leaves us with 317.
Take the next digit (3) from the dividend and append it to 317, then repeat: 3173 / 642

Let's proceed to step 8:
642 goes into 3173 4 times with a remainder of 605.
Record the quotient 4 as the next digit in the result. 
Result so far: 135614.0
If we subtract 2568 from 3173, we get 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Moving on to step 9:
642 can be fit into 6050 9 times, resulting in a remainder of 272.
Record the quotient 9 as the next digit in the result. 
Result so far: 135614.9
Subtract 5778 from 6050 to get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 10:
642 goes into 2720 4 times with a remainder of 152.
Write down 4 as next digit of the result. 
Result so far: 135614.94
The remainder is 152 after subtracting 2568 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 11:
642 can be fit into 1520 2 times, resulting in a remainder of 236.
Record the quotient 2 as the next digit in the result. 
Result so far: 135614.942
The remainder is 236 after subtracting 1284 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Let's proceed to step 12:
2360 divided by 642 is 3 with a remainder of 434.
The number 3 becomes the next digit in our result. 
Result so far: 135614.9423
Subtract 1926 from 2360 to get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Step 13:
4340 divided by 642 is 6 with a remainder of 488.
Put 6 as the next digit of the answer. 
Result so far: 135614.94236
The remainder is 488 after subtracting 3852 from 4340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Going ahead to step 14:
642 can be fit into 4880 7 times, resulting in a remainder of 386.
The next digit of our result is 7. 
Result so far: 135614.942367
Subtract 4494 from 4880 to get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Going ahead to step 15:
3860 divided by 642 is 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 135614.9423676
The remainder is 8 after subtracting 3852 from 3860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 16:
642 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 135614.9423676
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final outcome is 135614.9423676, with a leftover of 8e-08.
