We're dividing 77509814 by 610 
We want to divide 77509814 by 610.

Advancing to step 1:
If we divide 7 by 610, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 610

Moving on to step 2:
610 goes into 77 0 times with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Take the next digit (5) from the dividend and append it to 77, then repeat: 775 / 610

Step 3:
The number 610 fits into 775 1 times, leaving a remainder of 165.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 610 from 775 and we're left with 165.
Take the next digit (0) from the dividend and append it to 165, then repeat: 1650 / 610

Advancing to step 4:
610 goes into 1650 2 times with a remainder of 430.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 1220 away from 1650, we end up with 430.
Take the next digit (9) from the dividend and append it to 430, then repeat: 4309 / 610

Advancing to step 5:
When dividing 4309 by 610, we get 7 with a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 127.0
Subtract 4270 from 4309 to get 39.
Bring next digit (8) of the dividend behind the 39 and repeat the process: 398 / 610

Let's proceed to step 6:
If we divide 398 by 610, we get 0 and a remainder of 398.
The next digit of our result is 0. 
Result so far: 1270.0
Subtract 0 from 398 to get 398.
Grab the next digit (1) from the dividend, add it to 398, then carry on: 3981 / 610

Moving on to step 7:
If we divide 3981 by 610, we get 6 and a remainder of 321.
Use 6 as the next digit of our solution. 
Result so far: 12706.0
Deduct 3660 from 3981 and we're left with 321.
Take the next digit (4) from the dividend and append it to 321, then repeat: 3214 / 610

Going ahead to step 8:
610 can be fit into 3214 5 times, resulting in a remainder of 164.
The number 5 becomes the next digit in our result. 
Result so far: 127065.0
If we subtract 3050 from 3214, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 9:
610 goes into 1640 2 times with a remainder of 420.
Put 2 as the next digit of the answer. 
Result so far: 127065.2
Deduct 1220 from 1640 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 10:
When dividing 4200 by 610, we get 6 with a remainder of 540.
Record the quotient 6 as the next digit in the result. 
Result so far: 127065.26
Deduct 3660 from 4200 and we're left with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Going ahead to step 11:
5400 divided by 610 is 8 with a remainder of 520.
Put 8 as the next digit of the answer. 
Result so far: 127065.268
If we subtract 4880 from 5400, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 12:
When dividing 5200 by 610, we get 8 with a remainder of 320.
The next digit of our result is 8. 
Result so far: 127065.2688
Deduct 4880 from 5200 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The quotient of the division is 127065.2688, and the remainder is 0.0032.
