We divide 64576891 by 210
Let's see how many times 210 fits into 64576891.

Step 1:
The number 210 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 210

Moving on to step 2:
When dividing 64 by 210, we get 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Grab the next digit (5) from the dividend, add it to 64, then carry on: 645 / 210

Advancing to step 3:
If we divide 645 by 210, we get 3 and a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 15 after subtracting 630 from 645.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 210

On to step 4:
If we divide 157 by 210, we get 0 and a remainder of 157.
Use 0 as the next digit of our solution. 
Result so far: 30.0
If we take 0 away from 157, we end up with 157.
Include the next digit (6) from the dividend after 157, then repeat: 1576 / 210

Advancing to step 5:
210 goes into 1576 7 times with a remainder of 106.
Put 7 as the next digit of the answer. 
Result so far: 307.0
Subtract 1470 from 1576 to get 106.
Take the next digit (8) from the dividend and append it to 106, then repeat: 1068 / 210

Advancing to step 6:
When dividing 1068 by 210, we get 5 with a remainder of 18.
The next digit of our result is 5. 
Result so far: 3075.0
The remainder is 18 after subtracting 1050 from 1068.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 210

Going ahead to step 7:
If we divide 189 by 210, we get 0 and a remainder of 189.
Put 0 as the next digit of the answer. 
Result so far: 30750.0
Subtract 0 from 189 to get 189.
Grab the next digit (1) from the dividend, add it to 189, then carry on: 1891 / 210

Going ahead to step 8:
210 goes into 1891 9 times with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 307509.0
Subtracting 1890 from 1891 leaves us 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.

Let's proceed to step 9:
When dividing 10 by 210, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 307509.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
If we divide 100 by 210, we get 0 and a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 307509.0
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

In conclusion, the division gives 307509.0 with a balance of 0.1.
