66239730 ÷ 670 
We're looking to find how many times 670 goes into 66239730.

On to step 1:
When dividing 6 by 670, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 670

Going ahead to step 2:
If we divide 66 by 670, we get 0 and a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Grab the next digit (2) from the dividend, add it to 66, then carry on: 662 / 670

Going ahead to step 3:
If we divide 662 by 670, we get 0 and a remainder of 662.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 662, we end up with 662.
Take the next digit (3) from the dividend and append it to 662, then repeat: 6623 / 670

Advancing to step 4:
670 can be fit into 6623 9 times, resulting in a remainder of 593.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 6030 from 6623, we get 593.
Take the next digit (9) from the dividend and append it to 593, then repeat: 5939 / 670

On to step 5:
670 goes into 5939 8 times with a remainder of 579.
The next digit of our result is 8. 
Result so far: 98.0
If we subtract 5360 from 5939, we get 579.
Include the next digit (7) from the dividend after 579, then repeat: 5797 / 670

Advancing to step 6:
The number 670 fits into 5797 8 times, leaving a remainder of 437.
Use 8 as the next digit of our solution. 
Result so far: 988.0
Subtract 5360 from 5797 to get 437.
Append the next digit (3) from the dividend to 437 and continue with: 4373 / 670

Going ahead to step 7:
670 goes into 4373 6 times with a remainder of 353.
The next digit of our result is 6. 
Result so far: 9886.0
Subtracting 4020 from 4373 leaves us with 353.
Include the next digit (0) from the dividend after 353, then repeat: 3530 / 670

Advancing to step 8:
670 can be fit into 3530 5 times, resulting in a remainder of 180.
The next digit of our result is 5. 
Result so far: 98865.0
If we take 3350 away from 3530, we end up with 180.
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 9:
The number 670 fits into 1800 2 times, leaving a remainder of 460.
Use 2 as the next digit of our solution. 
Result so far: 98865.2
The remainder is 460 after subtracting 1340 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 10:
670 can be fit into 4600 6 times, resulting in a remainder of 580.
The next digit of our result is 6. 
Result so far: 98865.26
If we subtract 4020 from 4600, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Step 11:
The number 670 fits into 5800 8 times, leaving a remainder of 440.
Put 8 as the next digit of the answer. 
Result so far: 98865.268
The remainder is 440 after subtracting 5360 from 5800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 12:
The number 670 fits into 4400 6 times, leaving a remainder of 380.
Record the quotient 6 as the next digit in the result. 
Result so far: 98865.2686
The remainder is 380 after subtracting 4020 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 13:
670 can be fit into 3800 5 times, resulting in a remainder of 450.
Write down 5 as next digit of the result. 
Result so far: 98865.26865
Deduct 3350 from 3800 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 14:
670 goes into 4500 6 times with a remainder of 480.
Use 6 as the next digit of our solution. 
Result so far: 98865.268656
Deduct 4020 from 4500 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 15:
If we divide 4800 by 670, we get 7 and a remainder of 110.
Write down 7 as next digit of the result. 
Result so far: 98865.2686567
The remainder is 110 after subtracting 4690 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 16:
1100 divided by 670 is 1 with a remainder of 430.
Record the quotient 1 as the next digit in the result. 
Result so far: 98865.26865671
If we subtract 670 from 1100, we get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Our division results in 98865.26865671 with a remaining 4.3e-07.
