We look at the division of 15770070 by 666 
We want to divide 15770070 by 666.

Let's proceed to step 1:
If we divide 1 by 666, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 666

Let's proceed to step 2:
If we divide 15 by 666, we get 0 and a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 666

Let's proceed to step 3:
666 goes into 157 0 times with a remainder of 157.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 157 leaves us with 157.
Bring next digit (7) of the dividend behind the 157 and repeat the process: 1577 / 666

Let's proceed to step 4:
1577 divided by 666 is 2 with a remainder of 245.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 1332 from 1577 and we're left with 245.
Take the next digit (0) from the dividend and append it to 245, then repeat: 2450 / 666

Going ahead to step 5:
When dividing 2450 by 666, we get 3 with a remainder of 452.
The next digit of our result is 3. 
Result so far: 23.0
If we subtract 1998 from 2450, we get 452.
Append the next digit (0) from the dividend to 452 and continue with: 4520 / 666

Going ahead to step 6:
666 can be fit into 4520 6 times, resulting in a remainder of 524.
Use 6 as the next digit of our solution. 
Result so far: 236.0
If we take 3996 away from 4520, we end up with 524.
Include the next digit (7) from the dividend after 524, then repeat: 5247 / 666

Let's proceed to step 7:
The number 666 fits into 5247 7 times, leaving a remainder of 585.
Use 7 as the next digit of our solution. 
Result so far: 2367.0
Subtracting 4662 from 5247 leaves us with 585.
Fetch the next digit (0) from the dividend, attach it to 585 and continue: 5850 / 666

Moving on to step 8:
When dividing 5850 by 666, we get 8 with a remainder of 522.
Use 8 as the next digit of our solution. 
Result so far: 23678.0
If we subtract 5328 from 5850, we get 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Moving on to step 9:
The number 666 fits into 5220 7 times, leaving a remainder of 558.
Record the quotient 7 as the next digit in the result. 
Result so far: 23678.7
Subtract 4662 from 5220 to get 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

On to step 10:
666 can be fit into 5580 8 times, resulting in a remainder of 252.
Use 8 as the next digit of our solution. 
Result so far: 23678.78
Deduct 5328 from 5580 and we're left with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 11:
666 can be fit into 2520 3 times, resulting in a remainder of 522.
Put 3 as the next digit of the answer. 
Result so far: 23678.783
If we subtract 1998 from 2520, we get 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Going ahead to step 12:
666 can be fit into 5220 7 times, resulting in a remainder of 558.
Put 7 as the next digit of the answer. 
Result so far: 23678.7837
Subtract 4662 from 5220 to get 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Step 13:
If we divide 5580 by 666, we get 8 and a remainder of 252.
Put 8 as the next digit of the answer. 
Result so far: 23678.78378
The remainder is 252 after subtracting 5328 from 5580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 14:
The number 666 fits into 2520 3 times, leaving a remainder of 522.
Write down 3 as next digit of the result. 
Result so far: 23678.783783
Subtract 1998 from 2520 to get 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Advancing to step 15:
666 can be fit into 5220 7 times, resulting in a remainder of 558.
Write down 7 as next digit of the result. 
Result so far: 23678.7837837
Subtracting 4662 from 5220 leaves us with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Step 16:
The number 666 fits into 5580 8 times, leaving a remainder of 252.
The number 8 becomes the next digit in our result. 
Result so far: 23678.78378378
Subtract 5328 from 5580 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

The final outcome is 23678.78378378, with a leftover of 2.52e-07.
