73148520 ÷ 430 
Our goal is to divide 73148520 by 430.

Let's proceed to step 1:
430 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 430

Advancing to step 2:
430 goes into 73 0 times with a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Take the next digit (1) from the dividend and append it to 73, then repeat: 731 / 430

Advancing to step 3:
When dividing 731 by 430, we get 1 with a remainder of 301.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 430 from 731 and we're left with 301.
Include the next digit (4) from the dividend after 301, then repeat: 3014 / 430

Let's proceed to step 4:
430 can be fit into 3014 7 times, resulting in a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtracting 3010 from 3014 leaves us with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 430

Moving on to step 5:
48 divided by 430 is 0 with a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 170.0
Subtract 0 from 48 to get 48.
Grab the next digit (5) from the dividend, add it to 48, then carry on: 485 / 430

Moving on to step 6:
430 can be fit into 485 1 times, resulting in a remainder of 55.
Put 1 as the next digit of the answer. 
Result so far: 1701.0
Subtract 430 from 485 to get 55.
Append the next digit (2) from the dividend to 55 and continue with: 552 / 430

Moving on to step 7:
If we divide 552 by 430, we get 1 and a remainder of 122.
The next digit of our result is 1. 
Result so far: 17011.0
Subtracting 430 from 552 leaves us with 122.
Fetch the next digit (0) from the dividend, attach it to 122 and continue: 1220 / 430

Moving on to step 8:
The number 430 fits into 1220 2 times, leaving a remainder of 360.
Use 2 as the next digit of our solution. 
Result so far: 170112.0
Subtracting 860 from 1220 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 9:
3600 divided by 430 is 8 with a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 170112.8
If we take 3440 away from 3600, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 10:
1600 divided by 430 is 3 with a remainder of 310.
Use 3 as the next digit of our solution. 
Result so far: 170112.83
Deduct 1290 from 1600 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 11:
3100 divided by 430 is 7 with a remainder of 90.
The next digit of our result is 7. 
Result so far: 170112.837
Deduct 3010 from 3100 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 12:
If we divide 900 by 430, we get 2 and a remainder of 40.
The next digit of our result is 2. 
Result so far: 170112.8372
If we take 860 away from 900, we end up 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.

Advancing to step 13:
When dividing 400 by 430, we get 0 with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 170112.8372
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 14:
When dividing 4000 by 430, we get 9 with a remainder of 130.
Use 9 as the next digit of our solution. 
Result so far: 170112.837209
Subtract 3870 from 4000 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.

Step 15:
The number 430 fits into 1300 3 times, leaving a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 170112.8372093
If we subtract 1290 from 1300, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 16:
The number 430 fits into 100 0 times, leaving a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 170112.8372093
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The quotient of the division is 170112.8372093, and the remainder is 1e-07.
