87138984 ÷ 654 
We want to figure out the number of times 87138984 can be divided by 654.

Moving on to step 1:
8 divided by 654 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 654

On to step 2:
When dividing 87 by 654, we get 0 with a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Include the next digit (1) from the dividend after 87, then repeat: 871 / 654

Step 3:
When dividing 871 by 654, we get 1 with a remainder of 217.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 654 from 871 and we're left with 217.
Append the next digit (3) from the dividend to 217 and continue with: 2173 / 654

Step 4:
654 goes into 2173 3 times with a remainder of 211.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 1962 from 2173, we get 211.
Take the next digit (8) from the dividend and append it to 211, then repeat: 2118 / 654

Moving on to step 5:
2118 divided by 654 is 3 with a remainder of 156.
The next digit of our result is 3. 
Result so far: 133.0
Subtract 1962 from 2118 to get 156.
Include the next digit (9) from the dividend after 156, then repeat: 1569 / 654

Step 6:
When dividing 1569 by 654, we get 2 with a remainder of 261.
Write down 2 as next digit of the result. 
Result so far: 1332.0
If we subtract 1308 from 1569, we get 261.
Grab the next digit (8) from the dividend, add it to 261, then carry on: 2618 / 654

Advancing to step 7:
The number 654 fits into 2618 4 times, leaving a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 13324.0
Deduct 2616 from 2618 and we're left with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 654

Step 8:
The number 654 fits into 24 0 times, leaving a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 133240.0
Deduct 0 from 24 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
240 divided by 654 is 0 with a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 133240.0
Subtract 0 from 240 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 10:
When dividing 2400 by 654, we get 3 with a remainder of 438.
Put 3 as the next digit of the answer. 
Result so far: 133240.03
Subtract 1962 from 2400 to get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

On to step 11:
When dividing 4380 by 654, we get 6 with a remainder of 456.
The number 6 becomes the next digit in our result. 
Result so far: 133240.036
If we take 3924 away from 4380, we end up with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Step 12:
654 goes into 4560 6 times with a remainder of 636.
Record the quotient 6 as the next digit in the result. 
Result so far: 133240.0366
Deduct 3924 from 4560 and we're left with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

The quotient of the division is 133240.0366, and the remainder is 0.00636.
