87137507 divided by 261 
We want to figure out the number of times 87137507 can be divided by 261.

On to step 1:
8 divided by 261 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 261

Let's proceed to step 2:
87 divided by 261 is 0 with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Take the next digit (1) from the dividend and append it to 87, then repeat: 871 / 261

Advancing to step 3:
871 divided by 261 is 3 with a remainder of 88.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 783 away from 871, we end up with 88.
Append the next digit (3) from the dividend to 88 and continue with: 883 / 261

Advancing to step 4:
261 can be fit into 883 3 times, resulting in a remainder of 100.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Subtracting 783 from 883 leaves us with 100.
Take the next digit (7) from the dividend and append it to 100, then repeat: 1007 / 261

On to step 5:
1007 divided by 261 is 3 with a remainder of 224.
Record the quotient 3 as the next digit in the result. 
Result so far: 333.0
If we take 783 away from 1007, we end up with 224.
Take the next digit (5) from the dividend and append it to 224, then repeat: 2245 / 261

Step 6:
When dividing 2245 by 261, we get 8 with a remainder of 157.
Write down 8 as next digit of the result. 
Result so far: 3338.0
The remainder is 157 after subtracting 2088 from 2245.
Fetch the next digit (0) from the dividend, attach it to 157 and continue: 1570 / 261

Let's proceed to step 7:
The number 261 fits into 1570 6 times, leaving a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 33386.0
If we take 1566 away from 1570, we end up with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 261

Going ahead to step 8:
261 can be fit into 47 0 times, resulting in a remainder of 47.
The number 0 becomes the next digit in our result. 
Result so far: 333860.0
Subtract 0 from 47 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 9:
When dividing 470 by 261, we get 1 with a remainder of 209.
The next digit of our result is 1. 
Result so far: 333860.1
Deduct 261 from 470 and we're left with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Going ahead to step 10:
If we divide 2090 by 261, we get 8 and a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 333860.18
Subtracting 2088 from 2090 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 11:
261 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 333860.18
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
When dividing 200 by 261, we get 0 with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 333860.18
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Our division results in 333860.18 with a remaining 0.002.
