Let's divide 21339948 by 154
We want to figure out the number of times 21339948 can be divided by 154.

Step 1:
When dividing 2 by 154, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 154

Step 2:
The number 154 fits into 21 0 times, leaving a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 154

Let's proceed to step 3:
If we divide 213 by 154, we get 1 and a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 154 from 213 to get 59.
Append the next digit (3) from the dividend to 59 and continue with: 593 / 154

Let's proceed to step 4:
When dividing 593 by 154, we get 3 with a remainder of 131.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 462 from 593 and we're left with 131.
Fetch the next digit (9) from the dividend, attach it to 131 and continue: 1319 / 154

Advancing to step 5:
The number 154 fits into 1319 8 times, leaving a remainder of 87.
Write down 8 as next digit of the result. 
Result so far: 138.0
Deduct 1232 from 1319 and we're left with 87.
Fetch the next digit (9) from the dividend, attach it to 87 and continue: 879 / 154

Moving on to step 6:
The number 154 fits into 879 5 times, leaving a remainder of 109.
The number 5 becomes the next digit in our result. 
Result so far: 1385.0
Subtracting 770 from 879 leaves us with 109.
Include the next digit (4) from the dividend after 109, then repeat: 1094 / 154

Advancing to step 7:
1094 divided by 154 is 7 with a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 13857.0
Deduct 1078 from 1094 and we're left with 16.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 154

Advancing to step 8:
154 can be fit into 168 1 times, resulting in a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 138571.0
If we take 154 away from 168, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 9:
154 goes into 140 0 times with a remainder of 140.
Put 0 as the next digit of the answer. 
Result so far: 138571.0
If we take 0 away from 140, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 10:
If we divide 1400 by 154, we get 9 and a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 138571.09
If we subtract 1386 from 1400, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 11:
If we divide 140 by 154, we get 0 and a remainder of 140.
Put 0 as the next digit of the answer. 
Result so far: 138571.09
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 12:
When dividing 1400 by 154, we get 9 with a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 138571.0909
If we take 1386 away from 1400, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 13:
154 goes into 140 0 times with a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 138571.0909
If we take 0 away from 140, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 14:
If we divide 1400 by 154, we get 9 and a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 138571.090909
If we subtract 1386 from 1400, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 15:
140 divided by 154 is 0 with a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 138571.090909
If we take 0 away from 140, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 16:
1400 divided by 154 is 9 with a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 138571.09090909
Subtracting 1386 from 1400 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 138571.09090909 and a remainder of 1.4e-08.
