We look at the division of 36991 by 87 
We're looking to find how many times 87 goes into 36991.

Advancing to step 1:
3 divided by 87 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 87

On to step 2:
If we divide 36 by 87, we get 0 and 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.
Append the next digit (9) from the dividend to 36 and continue with: 369 / 87

Going ahead to step 3:
87 can be fit into 369 4 times, resulting in a remainder of 21.
The next digit of our result is 4. 
Result so far: 4.0
If we take 348 away from 369, we end up with 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 87

Advancing to step 4:
The number 87 fits into 219 2 times, leaving a remainder of 45.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
The remainder is 45 after subtracting 174 from 219.
Fetch the next digit (1) from the dividend, attach it to 45 and continue: 451 / 87

Moving on to step 5:
451 divided by 87 is 5 with a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 425.0
Subtract 435 from 451 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 6:
The number 87 fits into 160 1 times, leaving a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 425.1
If we subtract 87 from 160, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 7:
When dividing 730 by 87, we get 8 with a remainder of 34.
The next digit of our result is 8. 
Result so far: 425.18
Subtract 696 from 730 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 8:
87 goes into 340 3 times with a remainder of 79.
Record the quotient 3 as the next digit in the result. 
Result so far: 425.183
Subtracting 261 from 340 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 9:
87 can be fit into 790 9 times, resulting in a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 425.1839
Deduct 783 from 790 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 10:
The number 87 fits into 70 0 times, leaving a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 425.1839
If we take 0 away from 70, we end up 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.

On to step 11:
87 can be fit into 700 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 425.183908
Subtract 696 from 700 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
40 divided by 87 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 425.183908
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
400 divided by 87 is 4 with a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 425.18390804
Subtract 348 from 400 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The quotient of the division is 425.18390804, and the remainder is 5.2e-08.
