87403160 divided by 39 
Our goal is to divide 87403160 by 39.

Advancing to step 1:
39 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 39

Step 2:
If we divide 87 by 39, we get 2 and a remainder of 9.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 78 from 87, we get 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 39

Moving on to step 3:
39 can be fit into 94 2 times, resulting in a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Deduct 78 from 94 and we're left with 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 39

Let's proceed to step 4:
The number 39 fits into 160 4 times, leaving a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 224.0
Subtracting 156 from 160 leaves us with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 39

Step 5:
When dividing 43 by 39, we get 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 2241.0
If we subtract 39 from 43, we get 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 39

Moving on to step 6:
39 can be fit into 41 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 22411.0
Subtract 39 from 41 to get 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 39

Let's proceed to step 7:
If we divide 26 by 39, we get 0 and a remainder of 26.
The next digit of our result is 0. 
Result so far: 224110.0
Subtracting 0 from 26 leaves us with 26.
Append the next digit (0) from the dividend to 26 and continue with: 260 / 39

Step 8:
39 goes into 260 6 times with a remainder of 26.
The next digit of our result is 6. 
Result so far: 2241106.0
Deduct 234 from 260 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 9:
If we divide 260 by 39, we get 6 and a remainder of 26.
The next digit of our result is 6. 
Result so far: 2241106.6
If we take 234 away from 260, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 10:
If we divide 260 by 39, we get 6 and a remainder of 26.
The next digit of our result is 6. 
Result so far: 2241106.66
If we take 234 away from 260, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Our division results in 2241106.66 with a remaining 0.026.
