77396486 divided by 607 
We're looking to find how many times 607 goes into 77396486.

On to step 1:
If we divide 7 by 607, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 607

Moving on to step 2:
607 can be fit into 77 0 times, resulting in a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Fetch the next digit (3) from the dividend, attach it to 77 and continue: 773 / 607

Moving on to step 3:
607 goes into 773 1 times with a remainder of 166.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 607 from 773 and we're left with 166.
Fetch the next digit (9) from the dividend, attach it to 166 and continue: 1669 / 607

Moving on to step 4:
607 goes into 1669 2 times with a remainder of 455.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 1214 away from 1669, we end up with 455.
Grab the next digit (6) from the dividend, add it to 455, then carry on: 4556 / 607

Going ahead to step 5:
4556 divided by 607 is 7 with a remainder of 307.
Record the quotient 7 as the next digit in the result. 
Result so far: 127.0
If we take 4249 away from 4556, we end up with 307.
Include the next digit (4) from the dividend after 307, then repeat: 3074 / 607

On to step 6:
When dividing 3074 by 607, we get 5 with a remainder of 39.
The number 5 becomes the next digit in our result. 
Result so far: 1275.0
Subtracting 3035 from 3074 leaves us with 39.
Append the next digit (8) from the dividend to 39 and continue with: 398 / 607

Moving on to step 7:
The number 607 fits into 398 0 times, leaving a remainder of 398.
Record the quotient 0 as the next digit in the result. 
Result so far: 12750.0
If we subtract 0 from 398, we get 398.
Fetch the next digit (6) from the dividend, attach it to 398 and continue: 3986 / 607

Let's proceed to step 8:
The number 607 fits into 3986 6 times, leaving a remainder of 344.
Put 6 as the next digit of the answer. 
Result so far: 127506.0
The remainder is 344 after subtracting 3642 from 3986.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Advancing to step 9:
When dividing 3440 by 607, we get 5 with a remainder of 405.
Record the quotient 5 as the next digit in the result. 
Result so far: 127506.5
Subtract 3035 from 3440 to get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Let's proceed to step 10:
The number 607 fits into 4050 6 times, leaving a remainder of 408.
Use 6 as the next digit of our solution. 
Result so far: 127506.56
Deduct 3642 from 4050 and we're left with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

On to step 11:
The number 607 fits into 4080 6 times, leaving a remainder of 438.
Record the quotient 6 as the next digit in the result. 
Result so far: 127506.566
The remainder is 438 after subtracting 3642 from 4080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

The final outcome is 127506.566, with a leftover of 0.0438.
