87905385 ÷ 290 
We want to figure out the number of times 87905385 can be divided by 290.

Going ahead to step 1:
The number 290 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 290

On to step 2:
290 can be fit into 87 0 times, resulting in a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Grab the next digit (9) from the dividend, add it to 87, then carry on: 879 / 290

Let's proceed to step 3:
879 divided by 290 is 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 870 away from 879, we end up with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 290

On to step 4:
When dividing 90 by 290, we get 0 with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we subtract 0 from 90, we get 90.
Fetch the next digit (5) from the dividend, attach it to 90 and continue: 905 / 290

Let's proceed to step 5:
905 divided by 290 is 3 with a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 303.0
If we take 870 away from 905, we end up with 35.
Append the next digit (3) from the dividend to 35 and continue with: 353 / 290

Step 6:
353 divided by 290 is 1 with a remainder of 63.
The number 1 becomes the next digit in our result. 
Result so far: 3031.0
Subtract 290 from 353 to get 63.
Append the next digit (8) from the dividend to 63 and continue with: 638 / 290

Going ahead to step 7:
290 goes into 638 2 times with a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 30312.0
The remainder is 58 after subtracting 580 from 638.
Append the next digit (5) from the dividend to 58 and continue with: 585 / 290

Let's proceed to step 8:
290 can be fit into 585 2 times, resulting in a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 303122.0
Subtract 580 from 585 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
When dividing 50 by 290, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 303122.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
The number 290 fits into 500 1 times, leaving a remainder of 210.
The number 1 becomes the next digit in our result. 
Result so far: 303122.01
Deduct 290 from 500 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 11:
290 can be fit into 2100 7 times, resulting in a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 303122.017
Subtracting 2030 from 2100 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 12:
If we divide 700 by 290, we get 2 and a remainder of 120.
The number 2 becomes the next digit in our result. 
Result so far: 303122.0172
If we take 580 away from 700, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 13:
1200 divided by 290 is 4 with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 303122.01724
If we take 1160 away from 1200, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 14:
290 can be fit into 400 1 times, resulting in a remainder of 110.
The next digit of our result is 1. 
Result so far: 303122.017241
If we take 290 away from 400, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 15:
If we divide 1100 by 290, we get 3 and a remainder of 230.
The number 3 becomes the next digit in our result. 
Result so far: 303122.0172413
If we subtract 870 from 1100, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 16:
The number 290 fits into 2300 7 times, leaving a remainder of 270.
The number 7 becomes the next digit in our result. 
Result so far: 303122.01724137
If we take 2030 away from 2300, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

After the division, we end up with 303122.01724137 and a remainder of 2.7e-07.
