84070503 ÷ 660 
We're looking to find how many times 660 goes into 84070503.

Advancing to step 1:
660 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 660

Step 2:
84 divided by 660 is 0 with a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 84, we end up with 84.
Bring next digit (0) of the dividend behind the 84 and repeat the process: 840 / 660

Moving on to step 3:
660 can be fit into 840 1 times, resulting in a remainder of 180.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 180 after subtracting 660 from 840.
Fetch the next digit (7) from the dividend, attach it to 180 and continue: 1807 / 660

Let's proceed to step 4:
When dividing 1807 by 660, we get 2 with a remainder of 487.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 1320 away from 1807, we end up with 487.
Include the next digit (0) from the dividend after 487, then repeat: 4870 / 660

On to step 5:
660 goes into 4870 7 times with a remainder of 250.
Use 7 as the next digit of our solution. 
Result so far: 127.0
Deduct 4620 from 4870 and we're left with 250.
Include the next digit (5) from the dividend after 250, then repeat: 2505 / 660

Let's proceed to step 6:
The number 660 fits into 2505 3 times, leaving a remainder of 525.
Put 3 as the next digit of the answer. 
Result so far: 1273.0
If we subtract 1980 from 2505, we get 525.
Append the next digit (0) from the dividend to 525 and continue with: 5250 / 660

Step 7:
When dividing 5250 by 660, we get 7 with a remainder of 630.
Record the quotient 7 as the next digit in the result. 
Result so far: 12737.0
Deduct 4620 from 5250 and we're left with 630.
Append the next digit (3) from the dividend to 630 and continue with: 6303 / 660

Step 8:
The number 660 fits into 6303 9 times, leaving a remainder of 363.
Put 9 as the next digit of the answer. 
Result so far: 127379.0
The remainder is 363 after subtracting 5940 from 6303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Moving on to step 9:
660 goes into 3630 5 times with a remainder of 330.
Use 5 as the next digit of our solution. 
Result so far: 127379.5
If we take 3300 away from 3630, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 10:
If we divide 3300 by 660, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 127379.55
The remainder is 0 after subtracting 3300 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 127379.55 and a remainder of 0.0.
