We look at the division of 38578814 by 210 
We want to figure out the number of times 38578814 can be divided by 210.

Let's proceed to step 1:
The number 210 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 210

Let's proceed to step 2:
210 can be fit into 38 0 times, resulting in a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Take the next digit (5) from the dividend and append it to 38, then repeat: 385 / 210

Let's proceed to step 3:
210 goes into 385 1 times with a remainder of 175.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 210 from 385 to get 175.
Bring next digit (7) of the dividend behind the 175 and repeat the process: 1757 / 210

Step 4:
When dividing 1757 by 210, we get 8 with a remainder of 77.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we subtract 1680 from 1757, we get 77.
Include the next digit (8) from the dividend after 77, then repeat: 778 / 210

On to step 5:
When dividing 778 by 210, we get 3 with a remainder of 148.
Use 3 as the next digit of our solution. 
Result so far: 183.0
Deduct 630 from 778 and we're left with 148.
Grab the next digit (8) from the dividend, add it to 148, then carry on: 1488 / 210

Step 6:
The number 210 fits into 1488 7 times, leaving a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 1837.0
If we take 1470 away from 1488, we end up with 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 210

Moving on to step 7:
210 can be fit into 181 0 times, resulting in a remainder of 181.
Put 0 as the next digit of the answer. 
Result so far: 18370.0
Deduct 0 from 181 and we're left with 181.
Bring next digit (4) of the dividend behind the 181 and repeat the process: 1814 / 210

Moving on to step 8:
210 goes into 1814 8 times with a remainder of 134.
Use 8 as the next digit of our solution. 
Result so far: 183708.0
If we subtract 1680 from 1814, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 9:
1340 divided by 210 is 6 with a remainder of 80.
Use 6 as the next digit of our solution. 
Result so far: 183708.6
If we take 1260 away from 1340, 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.

Going ahead to step 10:
When dividing 800 by 210, we get 3 with a remainder of 170.
Use 3 as the next digit of our solution. 
Result so far: 183708.63
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.

Step 11:
If we divide 1700 by 210, we get 8 and a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 183708.638
If we subtract 1680 from 1700, we get 20.
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:
200 divided by 210 is 0 with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 183708.638
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 13:
210 goes into 2000 9 times with a remainder of 110.
The next digit of our result is 9. 
Result so far: 183708.63809
The remainder is 110 after subtracting 1890 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 14:
When dividing 1100 by 210, we get 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 183708.638095
The remainder is 50 after subtracting 1050 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 15:
210 can be fit into 500 2 times, resulting in a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 183708.6380952
Deduct 420 from 500 and we're left 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.

Advancing to step 16:
If we divide 800 by 210, we get 3 and a remainder of 170.
Write down 3 as next digit of the result. 
Result so far: 183708.63809523
If we subtract 630 from 800, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

In conclusion, the division gives 183708.63809523 with a balance of 1.7e-07.
