We look at the division of 74389790 by 155 
We want to figure out the number of times 74389790 can be divided by 155.

Step 1:
If we divide 7 by 155, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 155

Let's proceed to step 2:
155 goes into 74 0 times with a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Fetch the next digit (3) from the dividend, attach it to 74 and continue: 743 / 155

Going ahead to step 3:
155 goes into 743 4 times with a remainder of 123.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 620 from 743, we get 123.
Grab the next digit (8) from the dividend, add it to 123, then carry on: 1238 / 155

Going ahead to step 4:
155 can be fit into 1238 7 times, resulting in a remainder of 153.
Write down 7 as next digit of the result. 
Result so far: 47.0
The remainder is 153 after subtracting 1085 from 1238.
Fetch the next digit (9) from the dividend, attach it to 153 and continue: 1539 / 155

Step 5:
The number 155 fits into 1539 9 times, leaving a remainder of 144.
Record the quotient 9 as the next digit in the result. 
Result so far: 479.0
The remainder is 144 after subtracting 1395 from 1539.
Take the next digit (7) from the dividend and append it to 144, then repeat: 1447 / 155

Moving on to step 6:
155 goes into 1447 9 times with a remainder of 52.
Record the quotient 9 as the next digit in the result. 
Result so far: 4799.0
The remainder is 52 after subtracting 1395 from 1447.
Include the next digit (9) from the dividend after 52, then repeat: 529 / 155

Going ahead to step 7:
If we divide 529 by 155, we get 3 and a remainder of 64.
Write down 3 as next digit of the result. 
Result so far: 47993.0
Subtract 465 from 529 to get 64.
Grab the next digit (0) from the dividend, add it to 64, then carry on: 640 / 155

Step 8:
155 goes into 640 4 times with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 479934.0
Subtracting 620 from 640 leaves us 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.

Moving on to step 9:
The number 155 fits into 200 1 times, leaving a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 479934.1
If we take 155 away from 200, we end up 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.

Let's proceed to step 10:
155 goes into 450 2 times with a remainder of 140.
The next digit of our result is 2. 
Result so far: 479934.12
The remainder is 140 after subtracting 310 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 11:
1400 divided by 155 is 9 with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 479934.129
Subtract 1395 from 1400 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 12:
50 divided by 155 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 479934.129
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 13:
155 goes into 500 3 times with a remainder of 35.
The next digit of our result is 3. 
Result so far: 479934.12903
If we take 465 away from 500, we end up 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 14:
155 can be fit into 350 2 times, resulting in a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 479934.129032
Subtract 310 from 350 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 15:
155 goes into 400 2 times with a remainder of 90.
The number 2 becomes the next digit in our result. 
Result so far: 479934.1290322
If we subtract 310 from 400, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

The final outcome is 479934.1290322, with a leftover of 9e-07.
