45375918 divided by 709 
We want to figure out the number of times 45375918 can be divided by 709.

Advancing to step 1:
If we divide 4 by 709, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 709

On to step 2:
When dividing 45 by 709, we get 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Append the next digit (3) from the dividend to 45 and continue with: 453 / 709

Going ahead to step 3:
709 can be fit into 453 0 times, resulting in a remainder of 453.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 453, we end up with 453.
Include the next digit (7) from the dividend after 453, then repeat: 4537 / 709

Let's proceed to step 4:
The number 709 fits into 4537 6 times, leaving a remainder of 283.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 4254 from 4537, we get 283.
Append the next digit (5) from the dividend to 283 and continue with: 2835 / 709

Step 5:
709 can be fit into 2835 3 times, resulting in a remainder of 708.
Put 3 as the next digit of the answer. 
Result so far: 63.0
If we subtract 2127 from 2835, we get 708.
Append the next digit (9) from the dividend to 708 and continue with: 7089 / 709

Step 6:
When dividing 7089 by 709, we get 9 with a remainder of 708.
Record the quotient 9 as the next digit in the result. 
Result so far: 639.0
The remainder is 708 after subtracting 6381 from 7089.
Grab the next digit (1) from the dividend, add it to 708, then carry on: 7081 / 709

On to step 7:
709 can be fit into 7081 9 times, resulting in a remainder of 700.
Put 9 as the next digit of the answer. 
Result so far: 6399.0
Deduct 6381 from 7081 and we're left with 700.
Include the next digit (8) from the dividend after 700, then repeat: 7008 / 709

Step 8:
7008 divided by 709 is 9 with a remainder of 627.
The number 9 becomes the next digit in our result. 
Result so far: 63999.0
The remainder is 627 after subtracting 6381 from 7008.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6270, and continue the process.

Going ahead to step 9:
When dividing 6270 by 709, we get 8 with a remainder of 598.
Use 8 as the next digit of our solution. 
Result so far: 63999.8
If we take 5672 away from 6270, we end up with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Advancing to step 10:
If we divide 5980 by 709, we get 8 and a remainder of 308.
Record the quotient 8 as the next digit in the result. 
Result so far: 63999.88
If we take 5672 away from 5980, we end up with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

After the division, we end up with 63999.88 and a remainder of 0.308.
