369389 divided by 87 
We're looking to find how many times 87 goes into 369389.

On to step 1:
When dividing 3 by 87, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 87

Moving on to step 2:
87 goes into 36 0 times with a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 36, we end up with 36.
Take the next digit (9) from the dividend and append it to 36, then repeat: 369 / 87

Advancing to step 3:
If we divide 369 by 87, we get 4 and a remainder of 21.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 348 away from 369, we end up with 21.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 87

Moving on to step 4:
When dividing 213 by 87, we get 2 with a remainder of 39.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Subtract 174 from 213 to get 39.
Include the next digit (8) from the dividend after 39, then repeat: 398 / 87

Step 5:
If we divide 398 by 87, we get 4 and a remainder of 50.
The next digit of our result is 4. 
Result so far: 424.0
If we take 348 away from 398, we end up with 50.
Grab the next digit (9) from the dividend, add it to 50, then carry on: 509 / 87

Moving on to step 6:
If we divide 509 by 87, we get 5 and a remainder of 74.
Use 5 as the next digit of our solution. 
Result so far: 4245.0
Subtract 435 from 509 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 7:
If we divide 740 by 87, we get 8 and a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 4245.8
If we subtract 696 from 740, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 8:
87 can be fit into 440 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 4245.85
Deduct 435 from 440 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
If we divide 50 by 87, we get 0 and a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 4245.85
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
When dividing 500 by 87, we get 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 4245.8505
If we take 435 away from 500, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 11:
650 divided by 87 is 7 with a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 4245.85057
Subtracting 609 from 650 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 12:
If we divide 410 by 87, we get 4 and a remainder of 62.
Record the quotient 4 as the next digit in the result. 
Result so far: 4245.850574
The remainder is 62 after subtracting 348 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 13:
620 divided by 87 is 7 with a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 4245.8505747
The remainder is 11 after subtracting 609 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 14:
87 can be fit into 110 1 times, resulting in a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 4245.85057471
Deduct 87 from 110 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final outcome is 4245.85057471, with a leftover of 2.3e-08.
