21372341 ÷ 545 
We want to divide 21372341 by 545.

Let's proceed to step 1:
2 divided by 545 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 545

Moving on to step 2:
When dividing 21 by 545, we get 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 545

Step 3:
545 can be fit into 213 0 times, resulting in a remainder of 213.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 213 and we're left with 213.
Include the next digit (7) from the dividend after 213, then repeat: 2137 / 545

Going ahead to step 4:
The number 545 fits into 2137 3 times, leaving a remainder of 502.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 1635 from 2137 and we're left with 502.
Include the next digit (2) from the dividend after 502, then repeat: 5022 / 545

Moving on to step 5:
545 can be fit into 5022 9 times, resulting in a remainder of 117.
Use 9 as the next digit of our solution. 
Result so far: 39.0
Subtract 4905 from 5022 to get 117.
Append the next digit (3) from the dividend to 117 and continue with: 1173 / 545

Advancing to step 6:
545 can be fit into 1173 2 times, resulting in a remainder of 83.
Use 2 as the next digit of our solution. 
Result so far: 392.0
Subtract 1090 from 1173 to get 83.
Bring next digit (4) of the dividend behind the 83 and repeat the process: 834 / 545

Going ahead to step 7:
The number 545 fits into 834 1 times, leaving a remainder of 289.
Record the quotient 1 as the next digit in the result. 
Result so far: 3921.0
Subtract 545 from 834 to get 289.
Take the next digit (1) from the dividend and append it to 289, then repeat: 2891 / 545

Going ahead to step 8:
545 goes into 2891 5 times with a remainder of 166.
Record the quotient 5 as the next digit in the result. 
Result so far: 39215.0
If we subtract 2725 from 2891, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Going ahead to step 9:
If we divide 1660 by 545, we get 3 and a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 39215.3
The remainder is 25 after subtracting 1635 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
545 goes into 250 0 times with a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 39215.3
If we subtract 0 from 250, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 11:
The number 545 fits into 2500 4 times, leaving a remainder of 320.
Record the quotient 4 as the next digit in the result. 
Result so far: 39215.304
If we subtract 2180 from 2500, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 12:
3200 divided by 545 is 5 with a remainder of 475.
The number 5 becomes the next digit in our result. 
Result so far: 39215.3045
Subtracting 2725 from 3200 leaves us with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Advancing to step 13:
4750 divided by 545 is 8 with a remainder of 390.
Use 8 as the next digit of our solution. 
Result so far: 39215.30458
Subtracting 4360 from 4750 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Going ahead to step 14:
545 goes into 3900 7 times with a remainder of 85.
Write down 7 as next digit of the result. 
Result so far: 39215.304587
Subtracting 3815 from 3900 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 15:
545 can be fit into 850 1 times, resulting in a remainder of 305.
Put 1 as the next digit of the answer. 
Result so far: 39215.3045871
Subtract 545 from 850 to get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Step 16:
When dividing 3050 by 545, we get 5 with a remainder of 325.
Put 5 as the next digit of the answer. 
Result so far: 39215.30458715
Subtract 2725 from 3050 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

After the division, we end up with 39215.30458715 and a remainder of 3.25e-07.
