We look at the division of 87226155 by 642 
We want to figure out the number of times 87226155 can be divided by 642.

Moving on to step 1:
642 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 642

On to step 2:
87 divided by 642 is 0 with a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Fetch the next digit (2) from the dividend, attach it to 87 and continue: 872 / 642

Let's proceed to step 3:
872 divided by 642 is 1 with a remainder of 230.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 230 after subtracting 642 from 872.
Take the next digit (2) from the dividend and append it to 230, then repeat: 2302 / 642

On to step 4:
642 can be fit into 2302 3 times, resulting in a remainder of 376.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 1926 from 2302 leaves us with 376.
Append the next digit (6) from the dividend to 376 and continue with: 3766 / 642

Step 5:
3766 divided by 642 is 5 with a remainder of 556.
Use 5 as the next digit of our solution. 
Result so far: 135.0
Deduct 3210 from 3766 and we're left with 556.
Grab the next digit (1) from the dividend, add it to 556, then carry on: 5561 / 642

Going ahead to step 6:
The number 642 fits into 5561 8 times, leaving a remainder of 425.
The number 8 becomes the next digit in our result. 
Result so far: 1358.0
Subtracting 5136 from 5561 leaves us with 425.
Take the next digit (5) from the dividend and append it to 425, then repeat: 4255 / 642

Moving on to step 7:
When dividing 4255 by 642, we get 6 with a remainder of 403.
Write down 6 as next digit of the result. 
Result so far: 13586.0
Subtract 3852 from 4255 to get 403.
Bring next digit (5) of the dividend behind the 403 and repeat the process: 4035 / 642

Going ahead to step 8:
642 goes into 4035 6 times with a remainder of 183.
Put 6 as the next digit of the answer. 
Result so far: 135866.0
The remainder is 183 after subtracting 3852 from 4035.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Step 9:
642 can be fit into 1830 2 times, resulting in a remainder of 546.
The next digit of our result is 2. 
Result so far: 135866.2
The remainder is 546 after subtracting 1284 from 1830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Let's proceed to step 10:
If we divide 5460 by 642, we get 8 and a remainder of 324.
The next digit of our result is 8. 
Result so far: 135866.28
Subtract 5136 from 5460 to get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Step 11:
The number 642 fits into 3240 5 times, leaving a remainder of 30.
The next digit of our result is 5. 
Result so far: 135866.285
Subtract 3210 from 3240 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
When dividing 300 by 642, we get 0 with a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 135866.285
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 13:
642 goes into 3000 4 times with a remainder of 432.
Put 4 as the next digit of the answer. 
Result so far: 135866.28504
The remainder is 432 after subtracting 2568 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Going ahead to step 14:
If we divide 4320 by 642, we get 6 and a remainder of 468.
Put 6 as the next digit of the answer. 
Result so far: 135866.285046
If we subtract 3852 from 4320, we get 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Going ahead to step 15:
4680 divided by 642 is 7 with a remainder of 186.
Use 7 as the next digit of our solution. 
Result so far: 135866.2850467
If we subtract 4494 from 4680, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Moving on to step 16:
1860 divided by 642 is 2 with a remainder of 576.
The next digit of our result is 2. 
Result so far: 135866.28504672
Subtracting 1284 from 1860 leaves us with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

In conclusion, the division gives 135866.28504672 with a balance of 5.76e-07.
