Let's divide 79545621 by 73
We want to divide 79545621 by 73.

Step 1:
The number 73 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 73

Moving on to step 2:
When dividing 79 by 73, we get 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 6 after subtracting 73 from 79.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 73

Moving on to step 3:
When dividing 65 by 73, we get 0 with a remainder of 65.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 65 and we're left with 65.
Append the next digit (4) from the dividend to 65 and continue with: 654 / 73

On to step 4:
73 goes into 654 8 times with a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
If we subtract 584 from 654, we get 70.
Fetch the next digit (5) from the dividend, attach it to 70 and continue: 705 / 73

Moving on to step 5:
73 goes into 705 9 times with a remainder of 48.
The number 9 becomes the next digit in our result. 
Result so far: 1089.0
Subtracting 657 from 705 leaves us with 48.
Grab the next digit (6) from the dividend, add it to 48, then carry on: 486 / 73

Step 6:
73 goes into 486 6 times with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 10896.0
Deduct 438 from 486 and we're left with 48.
Append the next digit (2) from the dividend to 48 and continue with: 482 / 73

Step 7:
When dividing 482 by 73, we get 6 with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 108966.0
Subtract 438 from 482 to get 44.
Grab the next digit (1) from the dividend, add it to 44, then carry on: 441 / 73

Step 8:
441 divided by 73 is 6 with a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 1089666.0
Subtracting 438 from 441 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 9:
The number 73 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 1089666.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
The number 73 fits into 300 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 1089666.04
Subtracting 292 from 300 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
The number 73 fits into 80 1 times, leaving a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1089666.041
Subtracting 73 from 80 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 12:
If we divide 70 by 73, we get 0 and a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 1089666.041
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 13:
73 can be fit into 700 9 times, resulting in a remainder of 43.
The next digit of our result is 9. 
Result so far: 1089666.04109
Subtract 657 from 700 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 14:
73 can be fit into 430 5 times, resulting in a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 1089666.041095
If we take 365 away from 430, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 15:
If we divide 650 by 73, we get 8 and a remainder of 66.
The next digit of our result is 8. 
Result so far: 1089666.0410958
Deduct 584 from 650 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 16:
73 can be fit into 660 9 times, resulting in a remainder of 3.
The next digit of our result is 9. 
Result so far: 1089666.04109589
Deduct 657 from 660 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 1089666.04109589 with a remainder of 3e-09.
