30890073 ÷ 670 
We're looking to find how many times 670 goes into 30890073.

Going ahead to step 1:
If we divide 3 by 670, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 670

Step 2:
When dividing 30 by 670, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Grab the next digit (8) from the dividend, add it to 30, then carry on: 308 / 670

Going ahead to step 3:
When dividing 308 by 670, we get 0 with a remainder of 308.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 308 leaves us with 308.
Append the next digit (9) from the dividend to 308 and continue with: 3089 / 670

Advancing to step 4:
670 goes into 3089 4 times with a remainder of 409.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 2680 away from 3089, we end up with 409.
Take the next digit (0) from the dividend and append it to 409, then repeat: 4090 / 670

Let's proceed to step 5:
670 goes into 4090 6 times with a remainder of 70.
Write down 6 as next digit of the result. 
Result so far: 46.0
The remainder is 70 after subtracting 4020 from 4090.
Include the next digit (0) from the dividend after 70, then repeat: 700 / 670

On to step 6:
The number 670 fits into 700 1 times, leaving a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 461.0
Deduct 670 from 700 and we're left with 30.
Bring next digit (7) of the dividend behind the 30 and repeat the process: 307 / 670

Advancing to step 7:
307 divided by 670 is 0 with a remainder of 307.
Put 0 as the next digit of the answer. 
Result so far: 4610.0
Subtracting 0 from 307 leaves us with 307.
Bring next digit (3) of the dividend behind the 307 and repeat the process: 3073 / 670

Advancing to step 8:
If we divide 3073 by 670, we get 4 and a remainder of 393.
Write down 4 as next digit of the result. 
Result so far: 46104.0
Deduct 2680 from 3073 and we're left with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Moving on to step 9:
If we divide 3930 by 670, we get 5 and a remainder of 580.
Put 5 as the next digit of the answer. 
Result so far: 46104.5
Subtract 3350 from 3930 to 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.

Moving on to step 10:
670 goes into 5800 8 times with a remainder of 440.
The next digit of our result is 8. 
Result so far: 46104.58
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.

Step 11:
When dividing 4400 by 670, we get 6 with a remainder of 380.
The number 6 becomes the next digit in our result. 
Result so far: 46104.586
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.

Let's proceed to step 12:
When dividing 3800 by 670, we get 5 with a remainder of 450.
The next digit of our result is 5. 
Result so far: 46104.5865
If we take 3350 away from 3800, we end up 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.

Advancing to step 13:
The number 670 fits into 4500 6 times, leaving a remainder of 480.
Write down 6 as next digit of the result. 
Result so far: 46104.58656
If we subtract 4020 from 4500, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 14:
670 can be fit into 4800 7 times, resulting in a remainder of 110.
Write down 7 as next digit of the result. 
Result so far: 46104.586567
Deduct 4690 from 4800 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 15:
The number 670 fits into 1100 1 times, leaving a remainder of 430.
The next digit of our result is 1. 
Result so far: 46104.5865671
If we take 670 away from 1100, we end up with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Let's proceed to step 16:
When dividing 4300 by 670, we get 6 with a remainder of 280.
Write down 6 as next digit of the result. 
Result so far: 46104.58656716
If we subtract 4020 from 4300, 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.

The quotient of the division is 46104.58656716, and the remainder is 2.8e-07.
