Let's divide 54069794 by 210
Our goal is to divide 54069794 by 210.

Moving on to step 1:
The number 210 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 210

On to step 2:
The number 210 fits into 54 0 times, leaving a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Include the next digit (0) from the dividend after 54, then repeat: 540 / 210

Step 3:
When dividing 540 by 210, we get 2 with a remainder of 120.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 420 from 540 and we're left with 120.
Fetch the next digit (6) from the dividend, attach it to 120 and continue: 1206 / 210

On to step 4:
210 can be fit into 1206 5 times, resulting in a remainder of 156.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
The remainder is 156 after subtracting 1050 from 1206.
Fetch the next digit (9) from the dividend, attach it to 156 and continue: 1569 / 210

Advancing to step 5:
1569 divided by 210 is 7 with a remainder of 99.
Use 7 as the next digit of our solution. 
Result so far: 257.0
Subtract 1470 from 1569 to get 99.
Include the next digit (7) from the dividend after 99, then repeat: 997 / 210

Moving on to step 6:
210 goes into 997 4 times with a remainder of 157.
Record the quotient 4 as the next digit in the result. 
Result so far: 2574.0
Subtracting 840 from 997 leaves us with 157.
Grab the next digit (9) from the dividend, add it to 157, then carry on: 1579 / 210

Advancing to step 7:
1579 divided by 210 is 7 with a remainder of 109.
The number 7 becomes the next digit in our result. 
Result so far: 25747.0
Deduct 1470 from 1579 and we're left with 109.
Bring next digit (4) of the dividend behind the 109 and repeat the process: 1094 / 210

Moving on to step 8:
210 goes into 1094 5 times with a remainder of 44.
Write down 5 as next digit of the result. 
Result so far: 257475.0
The remainder is 44 after subtracting 1050 from 1094.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 9:
When dividing 440 by 210, we get 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 257475.2
Subtracting 420 from 440 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
If we divide 200 by 210, we get 0 and a remainder of 200.
The next digit of our result is 0. 
Result so far: 257475.2
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 11:
210 goes into 2000 9 times with a remainder of 110.
Use 9 as the next digit of our solution. 
Result so far: 257475.209
Subtract 1890 from 2000 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 12:
210 goes into 1100 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 257475.2095
Subtract 1050 from 1100 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 13:
The number 210 fits into 500 2 times, leaving a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 257475.20952
The remainder is 80 after subtracting 420 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 14:
210 goes into 800 3 times with a remainder of 170.
Use 3 as the next digit of our solution. 
Result so far: 257475.209523
Deduct 630 from 800 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 15:
If we divide 1700 by 210, we get 8 and a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 257475.2095238
The remainder is 20 after subtracting 1680 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 16:
200 divided by 210 is 0 with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 257475.2095238
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

In conclusion, the division gives 257475.2095238 with a balance of 2e-07.
