We look at the division of 77135480 by 601 
We want to figure out the number of times 77135480 can be divided by 601.

Step 1:
The number 601 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 601

On to step 2:
601 can be fit into 77 0 times, resulting in a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Include the next digit (1) from the dividend after 77, then repeat: 771 / 601

On to step 3:
601 goes into 771 1 times with a remainder of 170.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 601 from 771 leaves us with 170.
Grab the next digit (3) from the dividend, add it to 170, then carry on: 1703 / 601

On to step 4:
601 can be fit into 1703 2 times, resulting in a remainder of 501.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 501 after subtracting 1202 from 1703.
Grab the next digit (5) from the dividend, add it to 501, then carry on: 5015 / 601

Moving on to step 5:
The number 601 fits into 5015 8 times, leaving a remainder of 207.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
Subtracting 4808 from 5015 leaves us with 207.
Grab the next digit (4) from the dividend, add it to 207, then carry on: 2074 / 601

On to step 6:
2074 divided by 601 is 3 with a remainder of 271.
Record the quotient 3 as the next digit in the result. 
Result so far: 1283.0
If we take 1803 away from 2074, we end up with 271.
Grab the next digit (8) from the dividend, add it to 271, then carry on: 2718 / 601

Let's proceed to step 7:
The number 601 fits into 2718 4 times, leaving a remainder of 314.
The number 4 becomes the next digit in our result. 
Result so far: 12834.0
Deduct 2404 from 2718 and we're left with 314.
Bring next digit (0) of the dividend behind the 314 and repeat the process: 3140 / 601

Let's proceed to step 8:
If we divide 3140 by 601, we get 5 and a remainder of 135.
Record the quotient 5 as the next digit in the result. 
Result so far: 128345.0
The remainder is 135 after subtracting 3005 from 3140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 9:
If we divide 1350 by 601, we get 2 and a remainder of 148.
Use 2 as the next digit of our solution. 
Result so far: 128345.2
If we take 1202 away from 1350, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 10:
601 goes into 1480 2 times with a remainder of 278.
Use 2 as the next digit of our solution. 
Result so far: 128345.22
Subtract 1202 from 1480 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

In conclusion, the division gives 128345.22 with a balance of 0.278.
