Let's divide 15338421 by 670
We want to figure out the number of times 15338421 can be divided by 670.

Advancing to step 1:
670 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 670

Let's proceed to step 2:
670 goes into 15 0 times with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 670

Going ahead to step 3:
670 goes into 153 0 times with a remainder of 153.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 153, we get 153.
Bring next digit (3) of the dividend behind the 153 and repeat the process: 1533 / 670

Step 4:
The number 670 fits into 1533 2 times, leaving a remainder of 193.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 1340 from 1533 to get 193.
Include the next digit (8) from the dividend after 193, then repeat: 1938 / 670

Advancing to step 5:
670 can be fit into 1938 2 times, resulting in a remainder of 598.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Subtract 1340 from 1938 to get 598.
Fetch the next digit (4) from the dividend, attach it to 598 and continue: 5984 / 670

Let's proceed to step 6:
The number 670 fits into 5984 8 times, leaving a remainder of 624.
Use 8 as the next digit of our solution. 
Result so far: 228.0
Subtract 5360 from 5984 to get 624.
Include the next digit (2) from the dividend after 624, then repeat: 6242 / 670

Advancing to step 7:
The number 670 fits into 6242 9 times, leaving a remainder of 212.
Write down 9 as next digit of the result. 
Result so far: 2289.0
The remainder is 212 after subtracting 6030 from 6242.
Fetch the next digit (1) from the dividend, attach it to 212 and continue: 2121 / 670

On to step 8:
670 can be fit into 2121 3 times, resulting in a remainder of 111.
Record the quotient 3 as the next digit in the result. 
Result so far: 22893.0
If we take 2010 away from 2121, we end up with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

On to step 9:
1110 divided by 670 is 1 with a remainder of 440.
Write down 1 as next digit of the result. 
Result so far: 22893.1
If we take 670 away from 1110, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Let's proceed to step 10:
670 can be fit into 4400 6 times, resulting in a remainder of 380.
Record the quotient 6 as the next digit in the result. 
Result so far: 22893.16
Subtract 4020 from 4400 to get 380.
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 11:
670 goes into 3800 5 times with a remainder of 450.
Use 5 as the next digit of our solution. 
Result so far: 22893.165
Subtracting 3350 from 3800 leaves us 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.

Let's proceed to step 12:
670 can be fit into 4500 6 times, resulting in a remainder of 480.
Use 6 as the next digit of our solution. 
Result so far: 22893.1656
The remainder is 480 after subtracting 4020 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 13:
The number 670 fits into 4800 7 times, leaving a remainder of 110.
Write down 7 as next digit of the result. 
Result so far: 22893.16567
If we take 4690 away from 4800, we end up 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.

Moving on to step 14:
670 goes into 1100 1 times with a remainder of 430.
The number 1 becomes the next digit in our result. 
Result so far: 22893.165671
Deduct 670 from 1100 and we're left 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.

On to step 15:
When dividing 4300 by 670, we get 6 with a remainder of 280.
Use 6 as the next digit of our solution. 
Result so far: 22893.1656716
Deduct 4020 from 4300 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 16:
670 can be fit into 2800 4 times, resulting in a remainder of 120.
The next digit of our result is 4. 
Result so far: 22893.16567164
The remainder is 120 after subtracting 2680 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final result is 22893.16567164 with a remainder of 1.2e-07.
