We're dividing 45523603 by 210 
We want to figure out the number of times 45523603 can be divided by 210.

Advancing to step 1:
210 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 210

On to step 2:
210 can be fit into 45 0 times, resulting in a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Grab the next digit (5) from the dividend, add it to 45, then carry on: 455 / 210

Advancing to step 3:
The number 210 fits into 455 2 times, leaving a remainder of 35.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 420 from 455 and we're left with 35.
Fetch the next digit (2) from the dividend, attach it to 35 and continue: 352 / 210

On to step 4:
210 can be fit into 352 1 times, resulting in a remainder of 142.
Put 1 as the next digit of the answer. 
Result so far: 21.0
The remainder is 142 after subtracting 210 from 352.
Bring next digit (3) of the dividend behind the 142 and repeat the process: 1423 / 210

Let's proceed to step 5:
1423 divided by 210 is 6 with a remainder of 163.
Use 6 as the next digit of our solution. 
Result so far: 216.0
If we subtract 1260 from 1423, we get 163.
Grab the next digit (6) from the dividend, add it to 163, then carry on: 1636 / 210

On to step 6:
When dividing 1636 by 210, we get 7 with a remainder of 166.
Put 7 as the next digit of the answer. 
Result so far: 2167.0
The remainder is 166 after subtracting 1470 from 1636.
Include the next digit (0) from the dividend after 166, then repeat: 1660 / 210

Let's proceed to step 7:
If we divide 1660 by 210, we get 7 and a remainder of 190.
Use 7 as the next digit of our solution. 
Result so far: 21677.0
Subtracting 1470 from 1660 leaves us with 190.
Include the next digit (3) from the dividend after 190, then repeat: 1903 / 210

Moving on to step 8:
210 can be fit into 1903 9 times, resulting in a remainder of 13.
The next digit of our result is 9. 
Result so far: 216779.0
Deduct 1890 from 1903 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 9:
210 goes into 130 0 times with a remainder of 130.
Use 0 as the next digit of our solution. 
Result so far: 216779.0
Subtract 0 from 130 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 10:
210 goes into 1300 6 times with a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 216779.06
Deduct 1260 from 1300 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
When dividing 400 by 210, we get 1 with a remainder of 190.
Record the quotient 1 as the next digit in the result. 
Result so far: 216779.061
The remainder is 190 after subtracting 210 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 12:
The number 210 fits into 1900 9 times, leaving a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 216779.0619
Subtracting 1890 from 1900 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
100 divided by 210 is 0 with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 216779.0619
Subtracting 0 from 100 leaves us 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.

Going ahead to step 14:
1000 divided by 210 is 4 with a remainder of 160.
Use 4 as the next digit of our solution. 
Result so far: 216779.061904
The remainder is 160 after subtracting 840 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 15:
If we divide 1600 by 210, we get 7 and a remainder of 130.
Use 7 as the next digit of our solution. 
Result so far: 216779.0619047
Subtract 1470 from 1600 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 16:
1300 divided by 210 is 6 with a remainder of 40.
The next digit of our result is 6. 
Result so far: 216779.06190476
Subtracting 1260 from 1300 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 216779.06190476 with a balance of 4e-08.
