We divide 74274538 by 155
Our goal is to divide 74274538 by 155.

Step 1:
When dividing 7 by 155, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 155

Moving on to step 2:
155 goes into 74 0 times with a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 74 after subtracting 0 from 74.
Bring next digit (2) of the dividend behind the 74 and repeat the process: 742 / 155

Let's proceed to step 3:
742 divided by 155 is 4 with a remainder of 122.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 620 from 742, we get 122.
Fetch the next digit (7) from the dividend, attach it to 122 and continue: 1227 / 155

Step 4:
155 can be fit into 1227 7 times, resulting in a remainder of 142.
Use 7 as the next digit of our solution. 
Result so far: 47.0
The remainder is 142 after subtracting 1085 from 1227.
Append the next digit (4) from the dividend to 142 and continue with: 1424 / 155

Advancing to step 5:
The number 155 fits into 1424 9 times, leaving a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 479.0
If we take 1395 away from 1424, we end up with 29.
Append the next digit (5) from the dividend to 29 and continue with: 295 / 155

On to step 6:
If we divide 295 by 155, we get 1 and a remainder of 140.
The next digit of our result is 1. 
Result so far: 4791.0
The remainder is 140 after subtracting 155 from 295.
Include the next digit (3) from the dividend after 140, then repeat: 1403 / 155

Step 7:
The number 155 fits into 1403 9 times, leaving a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 47919.0
Deduct 1395 from 1403 and we're left with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 155

Let's proceed to step 8:
If we divide 88 by 155, we get 0 and a remainder of 88.
The next digit of our result is 0. 
Result so far: 479190.0
If we subtract 0 from 88, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 9:
155 goes into 880 5 times with a remainder of 105.
The next digit of our result is 5. 
Result so far: 479190.5
Deduct 775 from 880 and we're left 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.

Let's proceed to step 10:
If we divide 1050 by 155, we get 6 and a remainder of 120.
The number 6 becomes the next digit in our result. 
Result so far: 479190.56
Subtracting 930 from 1050 leaves us with 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 11:
When dividing 1200 by 155, we get 7 with a remainder of 115.
Record the quotient 7 as the next digit in the result. 
Result so far: 479190.567
If we take 1085 away from 1200, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Let's proceed to step 12:
155 can be fit into 1150 7 times, resulting in a remainder of 65.
Put 7 as the next digit of the answer. 
Result so far: 479190.5677
If we take 1085 away from 1150, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final result is 479190.5677 with a remainder of 0.00065.
