We're dividing 75395473 by 607 
We want to figure out the number of times 75395473 can be divided by 607.

On to step 1:
The number 607 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 607

Step 2:
The number 607 fits into 75 0 times, leaving a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Include the next digit (3) from the dividend after 75, then repeat: 753 / 607

Let's proceed to step 3:
If we divide 753 by 607, we get 1 and a remainder of 146.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 607 from 753, we get 146.
Fetch the next digit (9) from the dividend, attach it to 146 and continue: 1469 / 607

Advancing to step 4:
1469 divided by 607 is 2 with a remainder of 255.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 1214 from 1469 and we're left with 255.
Append the next digit (5) from the dividend to 255 and continue with: 2555 / 607

Let's proceed to step 5:
When dividing 2555 by 607, we get 4 with a remainder of 127.
Record the quotient 4 as the next digit in the result. 
Result so far: 124.0
Deduct 2428 from 2555 and we're left with 127.
Grab the next digit (4) from the dividend, add it to 127, then carry on: 1274 / 607

Let's proceed to step 6:
1274 divided by 607 is 2 with a remainder of 60.
The next digit of our result is 2. 
Result so far: 1242.0
The remainder is 60 after subtracting 1214 from 1274.
Take the next digit (7) from the dividend and append it to 60, then repeat: 607 / 607

Advancing to step 7:
If we divide 607 by 607, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 12421.0
Deduct 607 from 607 and we're left with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 607

Step 8:
607 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 124210.0
Deduct 0 from 3 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.

On to step 9:
When dividing 30 by 607, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 124210.0
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.

Step 10:
300 divided by 607 is 0 with a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 124210.0
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Our division results in 124210.0 with a remaining 0.3.
