80423951 ÷ 610 
We want to divide 80423951 by 610.

Let's proceed to step 1:
610 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 610

Advancing to step 2:
610 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Append the next digit (4) from the dividend to 80 and continue with: 804 / 610

Let's proceed to step 3:
The number 610 fits into 804 1 times, leaving a remainder of 194.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 610 away from 804, we end up with 194.
Take the next digit (2) from the dividend and append it to 194, then repeat: 1942 / 610

Advancing to step 4:
If we divide 1942 by 610, we get 3 and a remainder of 112.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 1830 from 1942, we get 112.
Bring next digit (3) of the dividend behind the 112 and repeat the process: 1123 / 610

Moving on to step 5:
1123 divided by 610 is 1 with a remainder of 513.
Put 1 as the next digit of the answer. 
Result so far: 131.0
The remainder is 513 after subtracting 610 from 1123.
Include the next digit (9) from the dividend after 513, then repeat: 5139 / 610

Advancing to step 6:
610 goes into 5139 8 times with a remainder of 259.
The next digit of our result is 8. 
Result so far: 1318.0
If we take 4880 away from 5139, we end up with 259.
Fetch the next digit (5) from the dividend, attach it to 259 and continue: 2595 / 610

Going ahead to step 7:
610 can be fit into 2595 4 times, resulting in a remainder of 155.
Use 4 as the next digit of our solution. 
Result so far: 13184.0
Deduct 2440 from 2595 and we're left with 155.
Grab the next digit (1) from the dividend, add it to 155, then carry on: 1551 / 610

Moving on to step 8:
The number 610 fits into 1551 2 times, leaving a remainder of 331.
Put 2 as the next digit of the answer. 
Result so far: 131842.0
Deduct 1220 from 1551 and we're left with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Advancing to step 9:
3310 divided by 610 is 5 with a remainder of 260.
Use 5 as the next digit of our solution. 
Result so far: 131842.5
Subtracting 3050 from 3310 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 10:
The number 610 fits into 2600 4 times, leaving a remainder of 160.
Record the quotient 4 as the next digit in the result. 
Result so far: 131842.54
If we take 2440 away from 2600, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 11:
1600 divided by 610 is 2 with a remainder of 380.
Put 2 as the next digit of the answer. 
Result so far: 131842.542
If we subtract 1220 from 1600, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 12:
If we divide 3800 by 610, we get 6 and a remainder of 140.
The next digit of our result is 6. 
Result so far: 131842.5426
Subtracting 3660 from 3800 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 13:
610 goes into 1400 2 times with a remainder of 180.
The next digit of our result is 2. 
Result so far: 131842.54262
The remainder is 180 after subtracting 1220 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 14:
When dividing 1800 by 610, we get 2 with a remainder of 580.
Put 2 as the next digit of the answer. 
Result so far: 131842.542622
Deduct 1220 from 1800 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Our division results in 131842.542622 with a remaining 5.8e-05.
