58121241 ÷ 987 
We want to figure out the number of times 58121241 can be divided by 987.

Step 1:
If we divide 5 by 987, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 987

Let's proceed to step 2:
When dividing 58 by 987, we get 0 with a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 58 after subtracting 0 from 58.
Grab the next digit (1) from the dividend, add it to 58, then carry on: 581 / 987

Step 3:
If we divide 581 by 987, we get 0 and a remainder of 581.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 581 to get 581.
Bring next digit (2) of the dividend behind the 581 and repeat the process: 5812 / 987

On to step 4:
987 can be fit into 5812 5 times, resulting in a remainder of 877.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 4935 from 5812, we get 877.
Fetch the next digit (1) from the dividend, attach it to 877 and continue: 8771 / 987

Moving on to step 5:
When dividing 8771 by 987, we get 8 with a remainder of 875.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
Subtracting 7896 from 8771 leaves us with 875.
Bring next digit (2) of the dividend behind the 875 and repeat the process: 8752 / 987

Advancing to step 6:
8752 divided by 987 is 8 with a remainder of 856.
Record the quotient 8 as the next digit in the result. 
Result so far: 588.0
The remainder is 856 after subtracting 7896 from 8752.
Take the next digit (4) from the dividend and append it to 856, then repeat: 8564 / 987

Step 7:
8564 divided by 987 is 8 with a remainder of 668.
Write down 8 as next digit of the result. 
Result so far: 5888.0
The remainder is 668 after subtracting 7896 from 8564.
Fetch the next digit (1) from the dividend, attach it to 668 and continue: 6681 / 987

Advancing to step 8:
987 goes into 6681 6 times with a remainder of 759.
The next digit of our result is 6. 
Result so far: 58886.0
Deduct 5922 from 6681 and we're left with 759.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7590, and continue the process.

Step 9:
When dividing 7590 by 987, we get 7 with a remainder of 681.
Record the quotient 7 as the next digit in the result. 
Result so far: 58886.7
Subtract 6909 from 7590 to get 681.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6810, and continue the process.

Advancing to step 10:
987 goes into 6810 6 times with a remainder of 888.
The next digit of our result is 6. 
Result so far: 58886.76
Subtracting 5922 from 6810 leaves us with 888.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8880, and continue the process.

Moving on to step 11:
987 goes into 8880 8 times with a remainder of 984.
Record the quotient 8 as the next digit in the result. 
Result so far: 58886.768
If we subtract 7896 from 8880, we get 984.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9840, and continue the process.

Step 12:
987 goes into 9840 9 times with a remainder of 957.
Write down 9 as next digit of the result. 
Result so far: 58886.7689
If we take 8883 away from 9840, we end up with 957.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9570, and continue the process.

Let's proceed to step 13:
When dividing 9570 by 987, we get 9 with a remainder of 687.
Record the quotient 9 as the next digit in the result. 
Result so far: 58886.76899
If we subtract 8883 from 9570, we get 687.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6870, and continue the process.

In conclusion, the division gives 58886.76899 with a balance of 0.000687.
