Let's divide 90620859 by 87
We're looking to find how many times 87 goes into 90620859.

Moving on to step 1:
87 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 87

On to step 2:
The number 87 fits into 90 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 87 from 90 to get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 87

Going ahead to step 3:
87 goes into 36 0 times with a remainder of 36.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 36 after subtracting 0 from 36.
Append the next digit (2) from the dividend to 36 and continue with: 362 / 87

Step 4:
When dividing 362 by 87, we get 4 with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 104.0
The remainder is 14 after subtracting 348 from 362.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 87

Going ahead to step 5:
87 can be fit into 140 1 times, resulting in a remainder of 53.
Use 1 as the next digit of our solution. 
Result so far: 1041.0
Deduct 87 from 140 and we're left with 53.
Take the next digit (8) from the dividend and append it to 53, then repeat: 538 / 87

Advancing to step 6:
538 divided by 87 is 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 10416.0
The remainder is 16 after subtracting 522 from 538.
Fetch the next digit (5) from the dividend, attach it to 16 and continue: 165 / 87

On to step 7:
87 goes into 165 1 times with a remainder of 78.
Write down 1 as next digit of the result. 
Result so far: 104161.0
If we take 87 away from 165, we end up with 78.
Include the next digit (9) from the dividend after 78, then repeat: 789 / 87

Advancing to step 8:
If we divide 789 by 87, we get 9 and a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 1041619.0
Subtracting 783 from 789 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.

Moving on to step 9:
60 divided by 87 is 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 1041619.0
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
87 can be fit into 600 6 times, resulting in a remainder of 78.
The number 6 becomes the next digit in our result. 
Result so far: 1041619.06
The remainder is 78 after subtracting 522 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 11:
87 can be fit into 780 8 times, resulting in a remainder of 84.
Write down 8 as next digit of the result. 
Result so far: 1041619.068
The remainder is 84 after subtracting 696 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 12:
87 can be fit into 840 9 times, resulting in a remainder of 57.
Put 9 as the next digit of the answer. 
Result so far: 1041619.0689
If we take 783 away from 840, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 13:
When dividing 570 by 87, we get 6 with a remainder of 48.
The next digit of our result is 6. 
Result so far: 1041619.06896
Subtract 522 from 570 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 14:
The number 87 fits into 480 5 times, leaving a remainder of 45.
The next digit of our result is 5. 
Result so far: 1041619.068965
The remainder is 45 after subtracting 435 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 15:
If we divide 450 by 87, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 1041619.0689655
Subtracting 435 from 450 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

In conclusion, the division gives 1041619.0689655 with a balance of 1.5e-07.
