87739660 divided by 423 
We're looking to find how many times 423 goes into 87739660.

Moving on to step 1:
8 divided by 423 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 423

Advancing to step 2:
The number 423 fits into 87 0 times, leaving a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Take the next digit (7) from the dividend and append it to 87, then repeat: 877 / 423

Step 3:
423 can be fit into 877 2 times, resulting in a remainder of 31.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 31 after subtracting 846 from 877.
Append the next digit (3) from the dividend to 31 and continue with: 313 / 423

Step 4:
The number 423 fits into 313 0 times, leaving a remainder of 313.
Use 0 as the next digit of our solution. 
Result so far: 20.0
The remainder is 313 after subtracting 0 from 313.
Include the next digit (9) from the dividend after 313, then repeat: 3139 / 423

Going ahead to step 5:
3139 divided by 423 is 7 with a remainder of 178.
The number 7 becomes the next digit in our result. 
Result so far: 207.0
If we subtract 2961 from 3139, we get 178.
Append the next digit (6) from the dividend to 178 and continue with: 1786 / 423

Advancing to step 6:
423 goes into 1786 4 times with a remainder of 94.
Put 4 as the next digit of the answer. 
Result so far: 2074.0
The remainder is 94 after subtracting 1692 from 1786.
Include the next digit (6) from the dividend after 94, then repeat: 946 / 423

Moving on to step 7:
When dividing 946 by 423, we get 2 with a remainder of 100.
Record the quotient 2 as the next digit in the result. 
Result so far: 20742.0
If we subtract 846 from 946, we get 100.
Bring next digit (0) of the dividend behind the 100 and repeat the process: 1000 / 423

Moving on to step 8:
423 goes into 1000 2 times with a remainder of 154.
Write down 2 as next digit of the result. 
Result so far: 207422.0
Subtract 846 from 1000 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Advancing to step 9:
423 goes into 1540 3 times with a remainder of 271.
Record the quotient 3 as the next digit in the result. 
Result so far: 207422.3
Deduct 1269 from 1540 and we're left with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

On to step 10:
423 goes into 2710 6 times with a remainder of 172.
Put 6 as the next digit of the answer. 
Result so far: 207422.36
Subtract 2538 from 2710 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 11:
If we divide 1720 by 423, we get 4 and a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 207422.364
If we take 1692 away from 1720, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 12:
The number 423 fits into 280 0 times, leaving a remainder of 280.
Use 0 as the next digit of our solution. 
Result so far: 207422.364
If we subtract 0 from 280, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 13:
423 can be fit into 2800 6 times, resulting in a remainder of 262.
The next digit of our result is 6. 
Result so far: 207422.36406
If we subtract 2538 from 2800, we get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Going ahead to step 14:
When dividing 2620 by 423, we get 6 with a remainder of 82.
The number 6 becomes the next digit in our result. 
Result so far: 207422.364066
Subtract 2538 from 2620 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

The final outcome is 207422.364066, with a leftover of 8.2e-06.
