54015259 divided by 209 
Let's see how many times 209 fits into 54015259.

Step 1:
209 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 209

On to step 2:
When dividing 54 by 209, we get 0 with a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 54 after subtracting 0 from 54.
Bring next digit (0) of the dividend behind the 54 and repeat the process: 540 / 209

Going ahead to step 3:
209 goes into 540 2 times with a remainder of 122.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 418 from 540 to get 122.
Bring next digit (1) of the dividend behind the 122 and repeat the process: 1221 / 209

Going ahead to step 4:
The number 209 fits into 1221 5 times, leaving a remainder of 176.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Deduct 1045 from 1221 and we're left with 176.
Bring next digit (5) of the dividend behind the 176 and repeat the process: 1765 / 209

Going ahead to step 5:
209 goes into 1765 8 times with a remainder of 93.
Put 8 as the next digit of the answer. 
Result so far: 258.0
Subtract 1672 from 1765 to get 93.
Fetch the next digit (2) from the dividend, attach it to 93 and continue: 932 / 209

Let's proceed to step 6:
209 goes into 932 4 times with a remainder of 96.
Record the quotient 4 as the next digit in the result. 
Result so far: 2584.0
If we take 836 away from 932, we end up with 96.
Grab the next digit (5) from the dividend, add it to 96, then carry on: 965 / 209

On to step 7:
209 goes into 965 4 times with a remainder of 129.
Put 4 as the next digit of the answer. 
Result so far: 25844.0
If we take 836 away from 965, we end up with 129.
Take the next digit (9) from the dividend and append it to 129, then repeat: 1299 / 209

Advancing to step 8:
209 goes into 1299 6 times with a remainder of 45.
Record the quotient 6 as the next digit in the result. 
Result so far: 258446.0
Deduct 1254 from 1299 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 9:
When dividing 450 by 209, we get 2 with a remainder of 32.
The next digit of our result is 2. 
Result so far: 258446.2
If we subtract 418 from 450, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
The number 209 fits into 320 1 times, leaving a remainder of 111.
Record the quotient 1 as the next digit in the result. 
Result so far: 258446.21
Subtracting 209 from 320 leaves us with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Let's proceed to step 11:
When dividing 1110 by 209, we get 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 258446.215
If we take 1045 away from 1110, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 12:
If we divide 650 by 209, we get 3 and a remainder of 23.
The next digit of our result is 3. 
Result so far: 258446.2153
Deduct 627 from 650 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 13:
209 goes into 230 1 times with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 258446.21531
Subtracting 209 from 230 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 14:
The number 209 fits into 210 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 258446.215311
If we take 209 away from 210, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 258446.215311 with a balance of 1e-07.
