99954789 divided by 87 
We want to figure out the number of times 99954789 can be divided by 87.

Going ahead to step 1:
The number 87 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 87

Moving on to step 2:
87 goes into 99 1 times with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 87 from 99 leaves us with 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 87

Moving on to step 3:
If we divide 129 by 87, we get 1 and a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 87 away from 129, we end up with 42.
Fetch the next digit (5) from the dividend, attach it to 42 and continue: 425 / 87

On to step 4:
When dividing 425 by 87, we get 4 with a remainder of 77.
Use 4 as the next digit of our solution. 
Result so far: 114.0
Deduct 348 from 425 and we're left with 77.
Fetch the next digit (4) from the dividend, attach it to 77 and continue: 774 / 87

On to step 5:
The number 87 fits into 774 8 times, leaving a remainder of 78.
The number 8 becomes the next digit in our result. 
Result so far: 1148.0
Deduct 696 from 774 and we're left with 78.
Include the next digit (7) from the dividend after 78, then repeat: 787 / 87

Advancing to step 6:
The number 87 fits into 787 9 times, leaving a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 11489.0
If we subtract 783 from 787, we get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 87

Going ahead to step 7:
The number 87 fits into 48 0 times, leaving a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 114890.0
If we subtract 0 from 48, we get 48.
Bring next digit (9) of the dividend behind the 48 and repeat the process: 489 / 87

Advancing to step 8:
87 goes into 489 5 times with a remainder of 54.
Record the quotient 5 as the next digit in the result. 
Result so far: 1148905.0
Subtracting 435 from 489 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 9:
540 divided by 87 is 6 with a remainder of 18.
The next digit of our result is 6. 
Result so far: 1148905.6
The remainder is 18 after subtracting 522 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
87 can be fit into 180 2 times, resulting in a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 1148905.62
Subtracting 174 from 180 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 11:
87 can be fit into 60 0 times, resulting in a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 1148905.62
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
When dividing 600 by 87, we get 6 with a remainder of 78.
Write down 6 as next digit of the result. 
Result so far: 1148905.6206
If we take 522 away from 600, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 13:
The number 87 fits into 780 8 times, leaving a remainder of 84.
Put 8 as the next digit of the answer. 
Result so far: 1148905.62068
Subtracting 696 from 780 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 14:
87 can be fit into 840 9 times, resulting in a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 1148905.620689
If we subtract 783 from 840, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 15:
87 goes into 570 6 times with a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 1148905.6206896
If we take 522 away from 570, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 16:
If we divide 480 by 87, we get 5 and a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 1148905.62068965
Subtract 435 from 480 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

After the division, we end up with 1148905.62068965 and a remainder of 4.5e-08.
