We look at the division of 74473299 by 421 
We want to figure out the number of times 74473299 can be divided by 421.

Advancing to step 1:
421 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 421

On to step 2:
If we divide 74 by 421, we get 0 and a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Bring next digit (4) of the dividend behind the 74 and repeat the process: 744 / 421

Going ahead to step 3:
If we divide 744 by 421, we get 1 and a remainder of 323.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 421 from 744 leaves us with 323.
Include the next digit (7) from the dividend after 323, then repeat: 3237 / 421

On to step 4:
421 goes into 3237 7 times with a remainder of 290.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Deduct 2947 from 3237 and we're left with 290.
Fetch the next digit (3) from the dividend, attach it to 290 and continue: 2903 / 421

Advancing to step 5:
If we divide 2903 by 421, we get 6 and a remainder of 377.
The next digit of our result is 6. 
Result so far: 176.0
Deduct 2526 from 2903 and we're left with 377.
Grab the next digit (2) from the dividend, add it to 377, then carry on: 3772 / 421

Moving on to step 6:
421 can be fit into 3772 8 times, resulting in a remainder of 404.
Write down 8 as next digit of the result. 
Result so far: 1768.0
Subtracting 3368 from 3772 leaves us with 404.
Take the next digit (9) from the dividend and append it to 404, then repeat: 4049 / 421

Advancing to step 7:
421 goes into 4049 9 times with a remainder of 260.
The number 9 becomes the next digit in our result. 
Result so far: 17689.0
Subtracting 3789 from 4049 leaves us with 260.
Include the next digit (9) from the dividend after 260, then repeat: 2609 / 421

Step 8:
When dividing 2609 by 421, we get 6 with a remainder of 83.
The number 6 becomes the next digit in our result. 
Result so far: 176896.0
Deduct 2526 from 2609 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 9:
421 can be fit into 830 1 times, resulting in a remainder of 409.
Use 1 as the next digit of our solution. 
Result so far: 176896.1
If we subtract 421 from 830, we get 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Moving on to step 10:
If we divide 4090 by 421, we get 9 and a remainder of 301.
Record the quotient 9 as the next digit in the result. 
Result so far: 176896.19
Deduct 3789 from 4090 and we're left with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Advancing to step 11:
If we divide 3010 by 421, we get 7 and a remainder of 63.
Use 7 as the next digit of our solution. 
Result so far: 176896.197
The remainder is 63 after subtracting 2947 from 3010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 12:
421 can be fit into 630 1 times, resulting in a remainder of 209.
The next digit of our result is 1. 
Result so far: 176896.1971
Subtracting 421 from 630 leaves us with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Let's proceed to step 13:
421 goes into 2090 4 times with a remainder of 406.
Put 4 as the next digit of the answer. 
Result so far: 176896.19714
Deduct 1684 from 2090 and we're left with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Let's proceed to step 14:
The number 421 fits into 4060 9 times, leaving a remainder of 271.
Write down 9 as next digit of the result. 
Result so far: 176896.197149
The remainder is 271 after subtracting 3789 from 4060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Advancing to step 15:
If we divide 2710 by 421, we get 6 and a remainder of 184.
Write down 6 as next digit of the result. 
Result so far: 176896.1971496
Deduct 2526 from 2710 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 16:
When dividing 1840 by 421, we get 4 with a remainder of 156.
Write down 4 as next digit of the result. 
Result so far: 176896.19714964
If we subtract 1684 from 1840, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

After the division, we end up with 176896.19714964 and a remainder of 1.56e-07.
