We look at the division of 64069557 by 210 
We want to figure out the number of times 64069557 can be divided by 210.

Moving on to step 1:
The number 210 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 210

Let's proceed to step 2:
210 can be fit into 64 0 times, resulting in a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Fetch the next digit (0) from the dividend, attach it to 64 and continue: 640 / 210

Let's proceed to step 3:
When dividing 640 by 210, we get 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 630 from 640, we get 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 210

Going ahead to step 4:
The number 210 fits into 106 0 times, leaving a remainder of 106.
Put 0 as the next digit of the answer. 
Result so far: 30.0
The remainder is 106 after subtracting 0 from 106.
Append the next digit (9) from the dividend to 106 and continue with: 1069 / 210

Advancing to step 5:
When dividing 1069 by 210, we get 5 with a remainder of 19.
Write down 5 as next digit of the result. 
Result so far: 305.0
If we subtract 1050 from 1069, we get 19.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 210

Going ahead to step 6:
195 divided by 210 is 0 with a remainder of 195.
Use 0 as the next digit of our solution. 
Result so far: 3050.0
If we take 0 away from 195, we end up with 195.
Take the next digit (5) from the dividend and append it to 195, then repeat: 1955 / 210

Moving on to step 7:
When dividing 1955 by 210, we get 9 with a remainder of 65.
Record the quotient 9 as the next digit in the result. 
Result so far: 30509.0
Subtract 1890 from 1955 to get 65.
Append the next digit (7) from the dividend to 65 and continue with: 657 / 210

Advancing to step 8:
If we divide 657 by 210, we get 3 and a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 305093.0
If we take 630 away from 657, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 9:
210 can be fit into 270 1 times, resulting in a remainder of 60.
The next digit of our result is 1. 
Result so far: 305093.1
Subtract 210 from 270 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 10:
If we divide 600 by 210, we get 2 and a remainder of 180.
Use 2 as the next digit of our solution. 
Result so far: 305093.12
The remainder is 180 after subtracting 420 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 11:
When dividing 1800 by 210, we get 8 with a remainder of 120.
Use 8 as the next digit of our solution. 
Result so far: 305093.128
If we subtract 1680 from 1800, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 12:
If we divide 1200 by 210, we get 5 and a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 305093.1285
Subtract 1050 from 1200 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 13:
The number 210 fits into 1500 7 times, leaving a remainder of 30.
Use 7 as the next digit of our solution. 
Result so far: 305093.12857
Subtract 1470 from 1500 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 14:
300 divided by 210 is 1 with a remainder of 90.
The number 1 becomes the next digit in our result. 
Result so far: 305093.128571
If we subtract 210 from 300, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 15:
When dividing 900 by 210, we get 4 with a remainder of 60.
The next digit of our result is 4. 
Result so far: 305093.1285714
Subtract 840 from 900 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 16:
If we divide 600 by 210, we get 2 and a remainder of 180.
The number 2 becomes the next digit in our result. 
Result so far: 305093.12857142
Subtracting 420 from 600 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The quotient of the division is 305093.12857142, and the remainder is 1.8e-07.
