2861810 ÷ 155 
We want to figure out the number of times 2861810 can be divided by 155.

On to step 1:
155 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 155

Let's proceed to step 2:
When dividing 28 by 155, we get 0 with a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Bring next digit (6) of the dividend behind the 28 and repeat the process: 286 / 155

Going ahead to step 3:
The number 155 fits into 286 1 times, leaving a remainder of 131.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 155 from 286 to get 131.
Fetch the next digit (1) from the dividend, attach it to 131 and continue: 1311 / 155

Moving on to step 4:
The number 155 fits into 1311 8 times, leaving a remainder of 71.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtract 1240 from 1311 to get 71.
Include the next digit (8) from the dividend after 71, then repeat: 718 / 155

Advancing to step 5:
155 goes into 718 4 times with a remainder of 98.
Use 4 as the next digit of our solution. 
Result so far: 184.0
Subtract 620 from 718 to get 98.
Append the next digit (1) from the dividend to 98 and continue with: 981 / 155

Step 6:
The number 155 fits into 981 6 times, leaving a remainder of 51.
Use 6 as the next digit of our solution. 
Result so far: 1846.0
If we take 930 away from 981, we end up with 51.
Append the next digit (0) from the dividend to 51 and continue with: 510 / 155

Step 7:
155 goes into 510 3 times with a remainder of 45.
The next digit of our result is 3. 
Result so far: 18463.0
Subtracting 465 from 510 leaves us 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.

Advancing to step 8:
If we divide 450 by 155, we get 2 and a remainder of 140.
The next digit of our result is 2. 
Result so far: 18463.2
Subtract 310 from 450 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 9:
155 can be fit into 1400 9 times, resulting in a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 18463.29
Deduct 1395 from 1400 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
50 divided by 155 is 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 18463.29
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
500 divided by 155 is 3 with a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 18463.2903
Deduct 465 from 500 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 12:
155 goes into 350 2 times with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 18463.29032
The remainder is 40 after subtracting 310 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
When dividing 400 by 155, we get 2 with a remainder of 90.
Use 2 as the next digit of our solution. 
Result so far: 18463.290322
The remainder is 90 after subtracting 310 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

In conclusion, the division gives 18463.290322 with a balance of 9e-06.
