We look at the division of 84574023 by 231 
We want to figure out the number of times 84574023 can be divided by 231.

Step 1:
231 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 231

Going ahead to step 2:
When dividing 84 by 231, we get 0 with a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 84 leaves us with 84.
Bring next digit (5) of the dividend behind the 84 and repeat the process: 845 / 231

Moving on to step 3:
231 goes into 845 3 times with a remainder of 152.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 693 from 845 leaves us with 152.
Take the next digit (7) from the dividend and append it to 152, then repeat: 1527 / 231

Let's proceed to step 4:
If we divide 1527 by 231, we get 6 and a remainder of 141.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
If we take 1386 away from 1527, we end up with 141.
Fetch the next digit (4) from the dividend, attach it to 141 and continue: 1414 / 231

Step 5:
If we divide 1414 by 231, we get 6 and a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 366.0
Subtracting 1386 from 1414 leaves us with 28.
Take the next digit (0) from the dividend and append it to 28, then repeat: 280 / 231

Step 6:
If we divide 280 by 231, we get 1 and a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 3661.0
Subtract 231 from 280 to get 49.
Append the next digit (2) from the dividend to 49 and continue with: 492 / 231

Let's proceed to step 7:
If we divide 492 by 231, we get 2 and a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 36612.0
Subtracting 462 from 492 leaves us with 30.
Bring next digit (3) of the dividend behind the 30 and repeat the process: 303 / 231

Let's proceed to step 8:
231 goes into 303 1 times with a remainder of 72.
Write down 1 as next digit of the result. 
Result so far: 366121.0
Subtracting 231 from 303 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 9:
When dividing 720 by 231, we get 3 with a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 366121.3
Deduct 693 from 720 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 10:
The number 231 fits into 270 1 times, leaving a remainder of 39.
The next digit of our result is 1. 
Result so far: 366121.31
Subtracting 231 from 270 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 11:
The number 231 fits into 390 1 times, leaving a remainder of 159.
Put 1 as the next digit of the answer. 
Result so far: 366121.311
Subtracting 231 from 390 leaves us with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Our division results in 366121.311 with a remaining 0.0159.
