We're dividing 5581420 by 145 
We want to divide 5581420 by 145.

Moving on to step 1:
145 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 145

Moving on to step 2:
145 can be fit into 55 0 times, resulting in a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Grab the next digit (8) from the dividend, add it to 55, then carry on: 558 / 145

Going ahead to step 3:
558 divided by 145 is 3 with a remainder of 123.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 435 away from 558, we end up with 123.
Bring next digit (1) of the dividend behind the 123 and repeat the process: 1231 / 145

Moving on to step 4:
The number 145 fits into 1231 8 times, leaving a remainder of 71.
Put 8 as the next digit of the answer. 
Result so far: 38.0
Deduct 1160 from 1231 and we're left with 71.
Grab the next digit (4) from the dividend, add it to 71, then carry on: 714 / 145

Let's proceed to step 5:
714 divided by 145 is 4 with a remainder of 134.
Record the quotient 4 as the next digit in the result. 
Result so far: 384.0
Subtracting 580 from 714 leaves us with 134.
Grab the next digit (2) from the dividend, add it to 134, then carry on: 1342 / 145

Moving on to step 6:
145 goes into 1342 9 times with a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 3849.0
If we take 1305 away from 1342, we end up with 37.
Append the next digit (0) from the dividend to 37 and continue with: 370 / 145

Moving on to step 7:
145 can be fit into 370 2 times, resulting in a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 38492.0
Subtracting 290 from 370 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 8:
The number 145 fits into 800 5 times, leaving a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 38492.5
Deduct 725 from 800 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 9:
145 goes into 750 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 38492.55
Deduct 725 from 750 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

In conclusion, the division gives 38492.55 with a balance of 0.025.
