We're dividing 15574016 by 210 
We're looking to find how many times 210 goes into 15574016.

Step 1:
210 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 210

Going ahead to step 2:
15 divided by 210 is 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 210

Moving on to step 3:
The number 210 fits into 155 0 times, leaving a remainder of 155.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 155, we end up with 155.
Take the next digit (7) from the dividend and append it to 155, then repeat: 1557 / 210

Advancing to step 4:
210 can be fit into 1557 7 times, resulting in a remainder of 87.
The next digit of our result is 7. 
Result so far: 7.0
If we take 1470 away from 1557, we end up with 87.
Fetch the next digit (4) from the dividend, attach it to 87 and continue: 874 / 210

Step 5:
The number 210 fits into 874 4 times, leaving a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
Subtract 840 from 874 to get 34.
Include the next digit (0) from the dividend after 34, then repeat: 340 / 210

On to step 6:
When dividing 340 by 210, we get 1 with a remainder of 130.
Write down 1 as next digit of the result. 
Result so far: 741.0
Subtract 210 from 340 to get 130.
Grab the next digit (1) from the dividend, add it to 130, then carry on: 1301 / 210

Advancing to step 7:
The number 210 fits into 1301 6 times, leaving a remainder of 41.
The next digit of our result is 6. 
Result so far: 7416.0
Subtract 1260 from 1301 to get 41.
Append the next digit (6) from the dividend to 41 and continue with: 416 / 210

Step 8:
210 can be fit into 416 1 times, resulting in a remainder of 206.
The number 1 becomes the next digit in our result. 
Result so far: 74161.0
Deduct 210 from 416 and we're left with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Step 9:
2060 divided by 210 is 9 with a remainder of 170.
Use 9 as the next digit of our solution. 
Result so far: 74161.9
The remainder is 170 after subtracting 1890 from 2060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 10:
1700 divided by 210 is 8 with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 74161.98
If we take 1680 away from 1700, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
If we divide 200 by 210, we get 0 and a remainder of 200.
The next digit of our result is 0. 
Result so far: 74161.98
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 12:
The number 210 fits into 2000 9 times, leaving a remainder of 110.
Put 9 as the next digit of the answer. 
Result so far: 74161.9809
Deduct 1890 from 2000 and we're left with 110.
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 13:
The number 210 fits into 1100 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 74161.98095
If we take 1050 away from 1100, we end up 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.

Moving on to step 14:
210 can be fit into 500 2 times, resulting in a remainder of 80.
Put 2 as the next digit of the answer. 
Result so far: 74161.980952
Subtract 420 from 500 to get 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 15:
If we divide 800 by 210, we get 3 and a remainder of 170.
The next digit of our result is 3. 
Result so far: 74161.9809523
The remainder is 170 after subtracting 630 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 16:
The number 210 fits into 1700 8 times, leaving a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 74161.98095238
Deduct 1680 from 1700 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 74161.98095238, with a leftover of 2e-08.
