We're dividing 87138141 by 986 
We want to figure out the number of times 87138141 can be divided by 986.

Going ahead to step 1:
986 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 986

Going ahead to step 2:
986 goes into 87 0 times with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Bring next digit (1) of the dividend behind the 87 and repeat the process: 871 / 986

Advancing to step 3:
The number 986 fits into 871 0 times, leaving a remainder of 871.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 871 leaves us with 871.
Append the next digit (3) from the dividend to 871 and continue with: 8713 / 986

Advancing to step 4:
8713 divided by 986 is 8 with a remainder of 825.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 7888 away from 8713, we end up with 825.
Bring next digit (8) of the dividend behind the 825 and repeat the process: 8258 / 986

Let's proceed to step 5:
When dividing 8258 by 986, we get 8 with a remainder of 370.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
The remainder is 370 after subtracting 7888 from 8258.
Grab the next digit (1) from the dividend, add it to 370, then carry on: 3701 / 986

Step 6:
3701 divided by 986 is 3 with a remainder of 743.
Write down 3 as next digit of the result. 
Result so far: 883.0
Subtract 2958 from 3701 to get 743.
Append the next digit (4) from the dividend to 743 and continue with: 7434 / 986

Going ahead to step 7:
7434 divided by 986 is 7 with a remainder of 532.
The number 7 becomes the next digit in our result. 
Result so far: 8837.0
Deduct 6902 from 7434 and we're left with 532.
Take the next digit (1) from the dividend and append it to 532, then repeat: 5321 / 986

On to step 8:
When dividing 5321 by 986, we get 5 with a remainder of 391.
Use 5 as the next digit of our solution. 
Result so far: 88375.0
If we subtract 4930 from 5321, we get 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Step 9:
If we divide 3910 by 986, we get 3 and a remainder of 952.
Use 3 as the next digit of our solution. 
Result so far: 88375.3
If we take 2958 away from 3910, we end up with 952.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9520, and continue the process.

Step 10:
If we divide 9520 by 986, we get 9 and a remainder of 646.
The number 9 becomes the next digit in our result. 
Result so far: 88375.39
The remainder is 646 after subtracting 8874 from 9520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

On to step 11:
When dividing 6460 by 986, we get 6 with a remainder of 544.
The number 6 becomes the next digit in our result. 
Result so far: 88375.396
Deduct 5916 from 6460 and we're left with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

On to step 12:
986 goes into 5440 5 times with a remainder of 510.
Put 5 as the next digit of the answer. 
Result so far: 88375.3965
Subtracting 4930 from 5440 leaves us with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Advancing to step 13:
5100 divided by 986 is 5 with a remainder of 170.
Record the quotient 5 as the next digit in the result. 
Result so far: 88375.39655
If we take 4930 away from 5100, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

In conclusion, the division gives 88375.39655 with a balance of 0.00017.
