We're dividing 42284099 by 155 
We want to figure out the number of times 42284099 can be divided by 155.

Moving on to step 1:
When dividing 4 by 155, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 155

Advancing to step 2:
155 goes into 42 0 times with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Fetch the next digit (2) from the dividend, attach it to 42 and continue: 422 / 155

Moving on to step 3:
When dividing 422 by 155, we get 2 with a remainder of 112.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 310 from 422 to get 112.
Include the next digit (8) from the dividend after 112, then repeat: 1128 / 155

Advancing to step 4:
1128 divided by 155 is 7 with a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
If we take 1085 away from 1128, we end up with 43.
Grab the next digit (4) from the dividend, add it to 43, then carry on: 434 / 155

Step 5:
When dividing 434 by 155, we get 2 with a remainder of 124.
The next digit of our result is 2. 
Result so far: 272.0
Subtracting 310 from 434 leaves us with 124.
Grab the next digit (0) from the dividend, add it to 124, then carry on: 1240 / 155

Advancing to step 6:
155 can be fit into 1240 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 2728.0
Deduct 1240 from 1240 and we're left with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 155

On to step 7:
155 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 27280.0
If we subtract 0 from 9, we get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 155

Step 8:
99 divided by 155 is 0 with a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 272800.0
Deduct 0 from 99 and we're left with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Let's proceed to step 9:
When dividing 990 by 155, we get 6 with a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 272800.6
The remainder is 60 after subtracting 930 from 990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
The number 155 fits into 600 3 times, leaving a remainder of 135.
Use 3 as the next digit of our solution. 
Result so far: 272800.63
If we subtract 465 from 600, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 11:
155 goes into 1350 8 times with a remainder of 110.
Put 8 as the next digit of the answer. 
Result so far: 272800.638
If we take 1240 away from 1350, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 12:
1100 divided by 155 is 7 with a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 272800.6387
If we subtract 1085 from 1100, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 13:
The number 155 fits into 150 0 times, leaving a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 272800.6387
The remainder is 150 after subtracting 0 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 14:
155 can be fit into 1500 9 times, resulting in a remainder of 105.
Put 9 as the next digit of the answer. 
Result so far: 272800.638709
If we take 1395 away from 1500, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 15:
If we divide 1050 by 155, we get 6 and a remainder of 120.
The next digit of our result is 6. 
Result so far: 272800.6387096
Subtract 930 from 1050 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 16:
When dividing 1200 by 155, we get 7 with a remainder of 115.
Write down 7 as next digit of the result. 
Result so far: 272800.63870967
Subtract 1085 from 1200 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

The final outcome is 272800.63870967, with a leftover of 1.15e-07.
