We're dividing 87353442 by 243 
Let's see how many times 243 fits into 87353442.

On to step 1:
When dividing 8 by 243, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 243

On to step 2:
243 goes into 87 0 times with a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Bring next digit (3) of the dividend behind the 87 and repeat the process: 873 / 243

Going ahead to step 3:
243 goes into 873 3 times with a remainder of 144.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 144 after subtracting 729 from 873.
Grab the next digit (5) from the dividend, add it to 144, then carry on: 1445 / 243

On to step 4:
When dividing 1445 by 243, we get 5 with a remainder of 230.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Subtracting 1215 from 1445 leaves us with 230.
Include the next digit (3) from the dividend after 230, then repeat: 2303 / 243

Step 5:
2303 divided by 243 is 9 with a remainder of 116.
Record the quotient 9 as the next digit in the result. 
Result so far: 359.0
If we take 2187 away from 2303, we end up with 116.
Append the next digit (4) from the dividend to 116 and continue with: 1164 / 243

Let's proceed to step 6:
When dividing 1164 by 243, we get 4 with a remainder of 192.
Put 4 as the next digit of the answer. 
Result so far: 3594.0
Subtracting 972 from 1164 leaves us with 192.
Bring next digit (4) of the dividend behind the 192 and repeat the process: 1924 / 243

Advancing to step 7:
243 can be fit into 1924 7 times, resulting in a remainder of 223.
Write down 7 as next digit of the result. 
Result so far: 35947.0
Subtracting 1701 from 1924 leaves us with 223.
Take the next digit (2) from the dividend and append it to 223, then repeat: 2232 / 243

Step 8:
243 goes into 2232 9 times with a remainder of 45.
The number 9 becomes the next digit in our result. 
Result so far: 359479.0
Subtracting 2187 from 2232 leaves us 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.

Step 9:
243 can be fit into 450 1 times, resulting in a remainder of 207.
The next digit of our result is 1. 
Result so far: 359479.1
Subtract 243 from 450 to get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Advancing to step 10:
243 can be fit into 2070 8 times, resulting in a remainder of 126.
The number 8 becomes the next digit in our result. 
Result so far: 359479.18
If we subtract 1944 from 2070, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 11:
When dividing 1260 by 243, we get 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 359479.185
Deduct 1215 from 1260 and we're left 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.

Going ahead to step 12:
If we divide 450 by 243, we get 1 and a remainder of 207.
Use 1 as the next digit of our solution. 
Result so far: 359479.1851
The remainder is 207 after subtracting 243 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Let's proceed to step 13:
If we divide 2070 by 243, we get 8 and a remainder of 126.
The next digit of our result is 8. 
Result so far: 359479.18518
Subtract 1944 from 2070 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Going ahead to step 14:
When dividing 1260 by 243, we get 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 359479.185185
If we subtract 1215 from 1260, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 15:
The number 243 fits into 450 1 times, leaving a remainder of 207.
The next digit of our result is 1. 
Result so far: 359479.1851851
Subtract 243 from 450 to get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Let's proceed to step 16:
The number 243 fits into 2070 8 times, leaving a remainder of 126.
Record the quotient 8 as the next digit in the result. 
Result so far: 359479.18518518
If we subtract 1944 from 2070, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

The final result is 359479.18518518 with a remainder of 1.26e-07.
