We look at the division of 64489425 by 790 
We're looking to find how many times 790 goes into 64489425.

Step 1:
When dividing 6 by 790, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 790

Going ahead to step 2:
When dividing 64 by 790, we get 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 790

On to step 3:
644 divided by 790 is 0 with a remainder of 644.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 644, we get 644.
Grab the next digit (8) from the dividend, add it to 644, then carry on: 6448 / 790

Going ahead to step 4:
When dividing 6448 by 790, we get 8 with a remainder of 128.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 6320 from 6448, we get 128.
Include the next digit (9) from the dividend after 128, then repeat: 1289 / 790

Advancing to step 5:
790 goes into 1289 1 times with a remainder of 499.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
Subtracting 790 from 1289 leaves us with 499.
Take the next digit (4) from the dividend and append it to 499, then repeat: 4994 / 790

On to step 6:
4994 divided by 790 is 6 with a remainder of 254.
Use 6 as the next digit of our solution. 
Result so far: 816.0
If we take 4740 away from 4994, we end up with 254.
Bring next digit (2) of the dividend behind the 254 and repeat the process: 2542 / 790

Let's proceed to step 7:
The number 790 fits into 2542 3 times, leaving a remainder of 172.
Put 3 as the next digit of the answer. 
Result so far: 8163.0
If we subtract 2370 from 2542, we get 172.
Fetch the next digit (5) from the dividend, attach it to 172 and continue: 1725 / 790

Going ahead to step 8:
The number 790 fits into 1725 2 times, leaving a remainder of 145.
The number 2 becomes the next digit in our result. 
Result so far: 81632.0
Subtracting 1580 from 1725 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Going ahead to step 9:
The number 790 fits into 1450 1 times, leaving a remainder of 660.
Write down 1 as next digit of the result. 
Result so far: 81632.1
If we take 790 away from 1450, we end up with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Moving on to step 10:
790 can be fit into 6600 8 times, resulting in a remainder of 280.
The number 8 becomes the next digit in our result. 
Result so far: 81632.18
Subtracting 6320 from 6600 leaves us 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.

Going ahead to step 11:
When dividing 2800 by 790, we get 3 with a remainder of 430.
The number 3 becomes the next digit in our result. 
Result so far: 81632.183
The remainder is 430 after subtracting 2370 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Let's proceed to step 12:
4300 divided by 790 is 5 with a remainder of 350.
Use 5 as the next digit of our solution. 
Result so far: 81632.1835
Subtract 3950 from 4300 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 13:
3500 divided by 790 is 4 with a remainder of 340.
Record the quotient 4 as the next digit in the result. 
Result so far: 81632.18354
If we subtract 3160 from 3500, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 14:
790 goes into 3400 4 times with a remainder of 240.
Write down 4 as next digit of the result. 
Result so far: 81632.183544
Deduct 3160 from 3400 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

In conclusion, the division gives 81632.183544 with a balance of 2.4e-05.
