58394057 divided by 210 
Our goal is to divide 58394057 by 210.

Moving on to step 1:
210 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 210

Moving on to step 2:
210 can be fit into 58 0 times, resulting in a remainder of 58.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 58, we end up with 58.
Bring next digit (3) of the dividend behind the 58 and repeat the process: 583 / 210

Step 3:
210 goes into 583 2 times with a remainder of 163.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 420 from 583 and we're left with 163.
Include the next digit (9) from the dividend after 163, then repeat: 1639 / 210

Let's proceed to step 4:
210 can be fit into 1639 7 times, resulting in a remainder of 169.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
If we take 1470 away from 1639, we end up with 169.
Fetch the next digit (4) from the dividend, attach it to 169 and continue: 1694 / 210

Moving on to step 5:
If we divide 1694 by 210, we get 8 and a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 278.0
If we take 1680 away from 1694, we end up with 14.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 210

Step 6:
210 can be fit into 140 0 times, resulting in a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 2780.0
Subtract 0 from 140 to get 140.
Bring next digit (5) of the dividend behind the 140 and repeat the process: 1405 / 210

Step 7:
If we divide 1405 by 210, we get 6 and a remainder of 145.
Write down 6 as next digit of the result. 
Result so far: 27806.0
If we take 1260 away from 1405, we end up with 145.
Take the next digit (7) from the dividend and append it to 145, then repeat: 1457 / 210

Going ahead to step 8:
1457 divided by 210 is 6 with a remainder of 197.
The next digit of our result is 6. 
Result so far: 278066.0
The remainder is 197 after subtracting 1260 from 1457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Step 9:
1970 divided by 210 is 9 with a remainder of 80.
The next digit of our result is 9. 
Result so far: 278066.9
If we take 1890 away from 1970, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 10:
When dividing 800 by 210, we get 3 with a remainder of 170.
Write down 3 as next digit of the result. 
Result so far: 278066.93
The remainder is 170 after subtracting 630 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 11:
210 can be fit into 1700 8 times, resulting in a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 278066.938
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.

Moving on to step 12:
When dividing 200 by 210, we get 0 with a remainder of 200.
The next digit of our result is 0. 
Result so far: 278066.938
Subtracting 0 from 200 leaves us 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.

Moving on to step 13:
The number 210 fits into 2000 9 times, leaving a remainder of 110.
The next digit of our result is 9. 
Result so far: 278066.93809
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.

Let's proceed to step 14:
The number 210 fits into 1100 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 278066.938095
If we take 1050 away from 1100, we end up 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 15:
500 divided by 210 is 2 with a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 278066.9380952
If we take 420 away from 500, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 16:
If we divide 800 by 210, we get 3 and a remainder of 170.
Record the quotient 3 as the next digit in the result. 
Result so far: 278066.93809523
If we take 630 away from 800, we end up 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.

After the division, we end up with 278066.93809523 and a remainder of 1.7e-07.
