28570946 ÷ 243 
We want to divide 28570946 by 243.

Advancing to step 1:
243 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 243

Step 2:
243 can be fit into 28 0 times, resulting in a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Include the next digit (5) from the dividend after 28, then repeat: 285 / 243

Step 3:
243 goes into 285 1 times with a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 243 from 285 and we're left with 42.
Bring next digit (7) of the dividend behind the 42 and repeat the process: 427 / 243

Let's proceed to step 4:
427 divided by 243 is 1 with a remainder of 184.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 243 from 427 to get 184.
Include the next digit (0) from the dividend after 184, then repeat: 1840 / 243

Step 5:
If we divide 1840 by 243, we get 7 and a remainder of 139.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
Subtracting 1701 from 1840 leaves us with 139.
Append the next digit (9) from the dividend to 139 and continue with: 1399 / 243

Going ahead to step 6:
The number 243 fits into 1399 5 times, leaving a remainder of 184.
Put 5 as the next digit of the answer. 
Result so far: 1175.0
If we take 1215 away from 1399, we end up with 184.
Bring next digit (4) of the dividend behind the 184 and repeat the process: 1844 / 243

Advancing to step 7:
The number 243 fits into 1844 7 times, leaving a remainder of 143.
Put 7 as the next digit of the answer. 
Result so far: 11757.0
The remainder is 143 after subtracting 1701 from 1844.
Fetch the next digit (6) from the dividend, attach it to 143 and continue: 1436 / 243

Let's proceed to step 8:
The number 243 fits into 1436 5 times, leaving a remainder of 221.
Record the quotient 5 as the next digit in the result. 
Result so far: 117575.0
If we take 1215 away from 1436, we end up with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Let's proceed to step 9:
The number 243 fits into 2210 9 times, leaving a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 117575.9
If we subtract 2187 from 2210, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 10:
If we divide 230 by 243, we get 0 and a remainder of 230.
Put 0 as the next digit of the answer. 
Result so far: 117575.9
The remainder is 230 after subtracting 0 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 11:
If we divide 2300 by 243, we get 9 and a remainder of 113.
The number 9 becomes the next digit in our result. 
Result so far: 117575.909
Deduct 2187 from 2300 and we're left with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

On to step 12:
243 can be fit into 1130 4 times, resulting in a remainder of 158.
Record the quotient 4 as the next digit in the result. 
Result so far: 117575.9094
If we take 972 away from 1130, we end up with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Let's proceed to step 13:
1580 divided by 243 is 6 with a remainder of 122.
Write down 6 as next digit of the result. 
Result so far: 117575.90946
If we subtract 1458 from 1580, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 14:
243 can be fit into 1220 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 117575.909465
If we subtract 1215 from 1220, we 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.

On to step 15:
When dividing 50 by 243, we get 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 117575.909465
Deduct 0 from 50 and we're left 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.

Going ahead to step 16:
When dividing 500 by 243, we get 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 117575.90946502
Deduct 486 from 500 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 117575.90946502 with a remaining 1.4e-08.
