76490919 ÷ 64 
Our goal is to divide 76490919 by 64.

Going ahead to step 1:
When dividing 7 by 64, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 64

Step 2:
64 can be fit into 76 1 times, resulting in a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 64 from 76 to get 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 64

On to step 3:
If we divide 124 by 64, we get 1 and a remainder of 60.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 64 away from 124, we end up with 60.
Take the next digit (9) from the dividend and append it to 60, then repeat: 609 / 64

Moving on to step 4:
If we divide 609 by 64, we get 9 and a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 119.0
Subtract 576 from 609 to get 33.
Grab the next digit (0) from the dividend, add it to 33, then carry on: 330 / 64

Step 5:
If we divide 330 by 64, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 1195.0
If we take 320 away from 330, we end up with 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 64

Step 6:
64 goes into 109 1 times with a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 11951.0
If we subtract 64 from 109, we get 45.
Include the next digit (1) from the dividend after 45, then repeat: 451 / 64

Step 7:
When dividing 451 by 64, we get 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 119517.0
Subtracting 448 from 451 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 64

Step 8:
64 can be fit into 39 0 times, resulting in a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 1195170.0
The remainder is 39 after subtracting 0 from 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 9:
64 goes into 390 6 times with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 1195170.6
If we subtract 384 from 390, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 10:
64 can be fit into 60 0 times, resulting in a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 1195170.6
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
600 divided by 64 is 9 with a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 1195170.609
Deduct 576 from 600 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 12:
240 divided by 64 is 3 with a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 1195170.6093
The remainder is 48 after subtracting 192 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 13:
The number 64 fits into 480 7 times, leaving a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 1195170.60937
If we take 448 away from 480, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 14:
When dividing 320 by 64, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 1195170.609375
Subtracting 320 from 320 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 15:
0 divided by 64 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1195170.609375
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 16:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1195170.609375
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 1195170.609375, and the remainder is 0.0.
