We look at the division of 74080346 by 155 
Our goal is to divide 74080346 by 155.

On to step 1:
155 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 155

Moving on to step 2:
155 can be fit into 74 0 times, resulting in a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Grab the next digit (0) from the dividend, add it to 74, then carry on: 740 / 155

Moving on to step 3:
155 goes into 740 4 times with a remainder of 120.
The next digit of our result is 4. 
Result so far: 4.0
If we take 620 away from 740, we end up with 120.
Fetch the next digit (8) from the dividend, attach it to 120 and continue: 1208 / 155

Advancing to step 4:
The number 155 fits into 1208 7 times, leaving a remainder of 123.
Put 7 as the next digit of the answer. 
Result so far: 47.0
Subtracting 1085 from 1208 leaves us with 123.
Fetch the next digit (0) from the dividend, attach it to 123 and continue: 1230 / 155

Let's proceed to step 5:
If we divide 1230 by 155, we get 7 and a remainder of 145.
Use 7 as the next digit of our solution. 
Result so far: 477.0
If we subtract 1085 from 1230, we get 145.
Append the next digit (3) from the dividend to 145 and continue with: 1453 / 155

Advancing to step 6:
1453 divided by 155 is 9 with a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 4779.0
If we take 1395 away from 1453, we end up with 58.
Grab the next digit (4) from the dividend, add it to 58, then carry on: 584 / 155

On to step 7:
584 divided by 155 is 3 with a remainder of 119.
Use 3 as the next digit of our solution. 
Result so far: 47793.0
Deduct 465 from 584 and we're left with 119.
Include the next digit (6) from the dividend after 119, then repeat: 1196 / 155

On to step 8:
155 goes into 1196 7 times with a remainder of 111.
Use 7 as the next digit of our solution. 
Result so far: 477937.0
If we take 1085 away from 1196, we end up with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Let's proceed to step 9:
155 can be fit into 1110 7 times, resulting in a remainder of 25.
Record the quotient 7 as the next digit in the result. 
Result so far: 477937.7
The remainder is 25 after subtracting 1085 from 1110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 10:
If we divide 250 by 155, we get 1 and a remainder of 95.
Write down 1 as next digit of the result. 
Result so far: 477937.71
Subtracting 155 from 250 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 11:
155 goes into 950 6 times with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 477937.716
Deduct 930 from 950 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
When dividing 200 by 155, we get 1 with a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 477937.7161
The remainder is 45 after subtracting 155 from 200.
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 13:
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: 477937.71612
If we take 310 away from 450, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 14:
155 goes into 1400 9 times with a remainder of 5.
The next digit of our result is 9. 
Result so far: 477937.716129
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.

Moving on to step 15:
155 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 477937.716129
If we subtract 0 from 50, we 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 16:
The number 155 fits into 500 3 times, leaving a remainder of 35.
The next digit of our result is 3. 
Result so far: 477937.71612903
Subtract 465 from 500 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 477937.71612903 and a remainder of 3.5e-08.
