78909187 ÷ 483 
We want to figure out the number of times 78909187 can be divided by 483.

Moving on to step 1:
When dividing 7 by 483, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 483

Let's proceed to step 2:
483 goes into 78 0 times with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Include the next digit (9) from the dividend after 78, then repeat: 789 / 483

On to step 3:
483 can be fit into 789 1 times, resulting in a remainder of 306.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 483 away from 789, we end up with 306.
Grab the next digit (0) from the dividend, add it to 306, then carry on: 3060 / 483

Step 4:
If we divide 3060 by 483, we get 6 and a remainder of 162.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtract 2898 from 3060 to get 162.
Include the next digit (9) from the dividend after 162, then repeat: 1629 / 483

Step 5:
483 can be fit into 1629 3 times, resulting in a remainder of 180.
Record the quotient 3 as the next digit in the result. 
Result so far: 163.0
Deduct 1449 from 1629 and we're left with 180.
Grab the next digit (1) from the dividend, add it to 180, then carry on: 1801 / 483

Going ahead to step 6:
483 can be fit into 1801 3 times, resulting in a remainder of 352.
Record the quotient 3 as the next digit in the result. 
Result so far: 1633.0
Deduct 1449 from 1801 and we're left with 352.
Fetch the next digit (8) from the dividend, attach it to 352 and continue: 3528 / 483

Step 7:
The number 483 fits into 3528 7 times, leaving a remainder of 147.
Put 7 as the next digit of the answer. 
Result so far: 16337.0
If we take 3381 away from 3528, we end up with 147.
Grab the next digit (7) from the dividend, add it to 147, then carry on: 1477 / 483

On to step 8:
483 goes into 1477 3 times with a remainder of 28.
Record the quotient 3 as the next digit in the result. 
Result so far: 163373.0
If we take 1449 away from 1477, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 9:
When dividing 280 by 483, we get 0 with a remainder of 280.
The number 0 becomes the next digit in our result. 
Result so far: 163373.0
Deduct 0 from 280 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 10:
483 can be fit into 2800 5 times, resulting in a remainder of 385.
Use 5 as the next digit of our solution. 
Result so far: 163373.05
Subtracting 2415 from 2800 leaves us with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Moving on to step 11:
3850 divided by 483 is 7 with a remainder of 469.
Use 7 as the next digit of our solution. 
Result so far: 163373.057
Subtract 3381 from 3850 to get 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

Advancing to step 12:
483 can be fit into 4690 9 times, resulting in a remainder of 343.
Use 9 as the next digit of our solution. 
Result so far: 163373.0579
Subtracting 4347 from 4690 leaves us with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Let's proceed to step 13:
When dividing 3430 by 483, we get 7 with a remainder of 49.
Put 7 as the next digit of the answer. 
Result so far: 163373.05797
The remainder is 49 after subtracting 3381 from 3430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 14:
490 divided by 483 is 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 163373.057971
Subtract 483 from 490 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 15:
483 goes into 70 0 times with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 163373.057971
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 16:
If we divide 700 by 483, we get 1 and a remainder of 217.
Use 1 as the next digit of our solution. 
Result so far: 163373.05797101
The remainder is 217 after subtracting 483 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

The final outcome is 163373.05797101, with a leftover of 2.17e-07.
