Let's divide 74638415 by 210
We want to divide 74638415 by 210.

Step 1:
210 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 210

Let's proceed to step 2:
When dividing 74 by 210, we get 0 with a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 74 and we're left with 74.
Append the next digit (6) from the dividend to 74 and continue with: 746 / 210

Going ahead to step 3:
The number 210 fits into 746 3 times, leaving a remainder of 116.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 630 from 746 to get 116.
Grab the next digit (3) from the dividend, add it to 116, then carry on: 1163 / 210

Advancing to step 4:
210 goes into 1163 5 times with a remainder of 113.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
The remainder is 113 after subtracting 1050 from 1163.
Include the next digit (8) from the dividend after 113, then repeat: 1138 / 210

Step 5:
210 goes into 1138 5 times with a remainder of 88.
Put 5 as the next digit of the answer. 
Result so far: 355.0
Subtracting 1050 from 1138 leaves us with 88.
Fetch the next digit (4) from the dividend, attach it to 88 and continue: 884 / 210

Let's proceed to step 6:
884 divided by 210 is 4 with a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 3554.0
Subtract 840 from 884 to get 44.
Grab the next digit (1) from the dividend, add it to 44, then carry on: 441 / 210

Going ahead to step 7:
The number 210 fits into 441 2 times, leaving a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 35542.0
Deduct 420 from 441 and we're left with 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 210

Going ahead to step 8:
215 divided by 210 is 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 355421.0
Subtracting 210 from 215 leaves us 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.

Let's proceed to step 9:
210 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 355421.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
When dividing 500 by 210, we get 2 with a remainder of 80.
The next digit of our result is 2. 
Result so far: 355421.02
If we subtract 420 from 500, we 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.

Step 11:
When dividing 800 by 210, we get 3 with a remainder of 170.
The next digit of our result is 3. 
Result so far: 355421.023
Subtract 630 from 800 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 12:
210 can be fit into 1700 8 times, resulting in a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 355421.0238
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.

Moving on to step 13:
210 can be fit into 200 0 times, resulting in a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 355421.0238
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 14:
The number 210 fits into 2000 9 times, leaving a remainder of 110.
The number 9 becomes the next digit in our result. 
Result so far: 355421.023809
If we take 1890 away from 2000, we end up 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.

Step 15:
The number 210 fits into 1100 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 355421.0238095
Subtract 1050 from 1100 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 16:
210 goes into 500 2 times with a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 355421.02380952
If we take 420 away from 500, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Our division results in 355421.02380952 with a remaining 8e-08.
