3115641 ÷ 87 
Let's see how many times 87 fits into 3115641.

Step 1:
87 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 87

Step 2:
The number 87 fits into 31 0 times, leaving a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Fetch the next digit (1) from the dividend, attach it to 31 and continue: 311 / 87

On to step 3:
87 can be fit into 311 3 times, resulting in a remainder of 50.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 261 from 311 leaves us with 50.
Grab the next digit (5) from the dividend, add it to 50, then carry on: 505 / 87

On to step 4:
The number 87 fits into 505 5 times, leaving a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 35.0
Subtracting 435 from 505 leaves us with 70.
Grab the next digit (6) from the dividend, add it to 70, then carry on: 706 / 87

Going ahead to step 5:
706 divided by 87 is 8 with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 358.0
If we subtract 696 from 706, we get 10.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 87

Advancing to step 6:
If we divide 104 by 87, we get 1 and a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 3581.0
If we take 87 away from 104, we end up with 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 87

Going ahead to step 7:
When dividing 171 by 87, we get 1 with a remainder of 84.
The next digit of our result is 1. 
Result so far: 35811.0
Subtract 87 from 171 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 8:
If we divide 840 by 87, we get 9 and a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 35811.9
The remainder is 57 after subtracting 783 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 9:
570 divided by 87 is 6 with a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 35811.96
Subtract 522 from 570 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 10:
87 goes into 480 5 times with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 35811.965
If we take 435 away from 480, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 11:
87 goes into 450 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 35811.9655
Subtracting 435 from 450 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 35811.9655, and the remainder is 0.00015.
