84581393 ÷ 23 
Let's see how many times 23 fits into 84581393.

On to step 1:
23 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
The remainder is 8 after subtracting 0 from 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 23

Step 2:
If we divide 84 by 23, we get 3 and a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 69 from 84, we get 15.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 23

Let's proceed to step 3:
155 divided by 23 is 6 with a remainder of 17.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
Deduct 138 from 155 and we're left with 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 23

Let's proceed to step 4:
When dividing 178 by 23, we get 7 with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 367.0
Deduct 161 from 178 and we're left with 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 23

Advancing to step 5:
23 can be fit into 171 7 times, resulting in a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 3677.0
Deduct 161 from 171 and we're left with 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 23

On to step 6:
If we divide 103 by 23, we get 4 and a remainder of 11.
The next digit of our result is 4. 
Result so far: 36774.0
Deduct 92 from 103 and we're left with 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 23

On to step 7:
23 can be fit into 119 5 times, resulting in a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 367745.0
Subtract 115 from 119 to get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 23

Advancing to step 8:
43 divided by 23 is 1 with a remainder of 20.
The next digit of our result is 1. 
Result so far: 3677451.0
If we subtract 23 from 43, we get 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:
23 goes into 200 8 times with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 3677451.8
If we take 184 away from 200, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
160 divided by 23 is 6 with a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 3677451.86
Deduct 138 from 160 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 11:
23 can be fit into 220 9 times, resulting in a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 3677451.869
The remainder is 13 after subtracting 207 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 12:
23 goes into 130 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 3677451.8695
Subtract 115 from 130 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 13:
23 goes into 150 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 3677451.86956
If we take 138 away from 150, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 14:
The number 23 fits into 120 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 3677451.869565
If we take 115 away from 120, we end up 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.

On to step 15:
When dividing 50 by 23, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 3677451.8695652
If we take 46 away from 50, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 16:
23 goes into 40 1 times with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 3677451.86956521
If we take 23 away from 40, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final outcome is 3677451.86956521, with a leftover of 1.7e-08.
