Let's divide 45225407 by 215
We're looking to find how many times 215 goes into 45225407.

Advancing to step 1:
The number 215 fits into 4 0 times, leaving 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.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 215

Let's proceed to step 2:
215 can be fit into 45 0 times, resulting in a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Take the next digit (2) from the dividend and append it to 45, then repeat: 452 / 215

Moving on to step 3:
The number 215 fits into 452 2 times, leaving a remainder of 22.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 430 from 452 and we're left with 22.
Fetch the next digit (2) from the dividend, attach it to 22 and continue: 222 / 215

Going ahead to step 4:
215 goes into 222 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we subtract 215 from 222, we get 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 215

Moving on to step 5:
215 can be fit into 75 0 times, resulting in a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 210.0
Subtracting 0 from 75 leaves us with 75.
Take the next digit (4) from the dividend and append it to 75, then repeat: 754 / 215

Step 6:
215 can be fit into 754 3 times, resulting in a remainder of 109.
The next digit of our result is 3. 
Result so far: 2103.0
If we subtract 645 from 754, we get 109.
Append the next digit (0) from the dividend to 109 and continue with: 1090 / 215

Advancing to step 7:
1090 divided by 215 is 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 21035.0
If we take 1075 away from 1090, we end up with 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 215

On to step 8:
If we divide 157 by 215, we get 0 and a remainder of 157.
Record the quotient 0 as the next digit in the result. 
Result so far: 210350.0
Deduct 0 from 157 and we're left with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Let's proceed to step 9:
215 goes into 1570 7 times with a remainder of 65.
Use 7 as the next digit of our solution. 
Result so far: 210350.7
If we take 1505 away from 1570, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 10:
215 goes into 650 3 times with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 210350.73
Deduct 645 from 650 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
50 divided by 215 is 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 210350.73
Deduct 0 from 50 and we're left 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.

Advancing to step 12:
500 divided by 215 is 2 with a remainder of 70.
The next digit of our result is 2. 
Result so far: 210350.7302
Subtract 430 from 500 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 13:
700 divided by 215 is 3 with a remainder of 55.
Put 3 as the next digit of the answer. 
Result so far: 210350.73023
Subtracting 645 from 700 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 14:
If we divide 550 by 215, we get 2 and a remainder of 120.
The number 2 becomes the next digit in our result. 
Result so far: 210350.730232
Deduct 430 from 550 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 15:
215 goes into 1200 5 times with a remainder of 125.
The number 5 becomes the next digit in our result. 
Result so far: 210350.7302325
Deduct 1075 from 1200 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 16:
215 can be fit into 1250 5 times, resulting in a remainder of 175.
Use 5 as the next digit of our solution. 
Result so far: 210350.73023255
If we subtract 1075 from 1250, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

The quotient of the division is 210350.73023255, and the remainder is 1.75e-07.
