We're dividing 10704280 by 621 
Our goal is to divide 10704280 by 621.

Advancing to step 1:
1 divided by 621 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 621

Moving on to step 2:
621 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 621

On to step 3:
If we divide 107 by 621, we get 0 and a remainder of 107.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 107 and we're left with 107.
Take the next digit (0) from the dividend and append it to 107, then repeat: 1070 / 621

Advancing to step 4:
1070 divided by 621 is 1 with a remainder of 449.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 621 from 1070 leaves us with 449.
Append the next digit (4) from the dividend to 449 and continue with: 4494 / 621

On to step 5:
621 goes into 4494 7 times with a remainder of 147.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtract 4347 from 4494 to get 147.
Append the next digit (2) from the dividend to 147 and continue with: 1472 / 621

Moving on to step 6:
1472 divided by 621 is 2 with a remainder of 230.
Record the quotient 2 as the next digit in the result. 
Result so far: 172.0
Subtract 1242 from 1472 to get 230.
Fetch the next digit (8) from the dividend, attach it to 230 and continue: 2308 / 621

Let's proceed to step 7:
The number 621 fits into 2308 3 times, leaving a remainder of 445.
Put 3 as the next digit of the answer. 
Result so far: 1723.0
If we subtract 1863 from 2308, we get 445.
Append the next digit (0) from the dividend to 445 and continue with: 4450 / 621

Step 8:
621 goes into 4450 7 times with a remainder of 103.
The next digit of our result is 7. 
Result so far: 17237.0
If we subtract 4347 from 4450, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Advancing to step 9:
621 can be fit into 1030 1 times, resulting in a remainder of 409.
Write down 1 as next digit of the result. 
Result so far: 17237.1
Subtract 621 from 1030 to get 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Step 10:
621 goes into 4090 6 times with a remainder of 364.
Record the quotient 6 as the next digit in the result. 
Result so far: 17237.16
If we take 3726 away from 4090, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Let's proceed to step 11:
When dividing 3640 by 621, we get 5 with a remainder of 535.
Put 5 as the next digit of the answer. 
Result so far: 17237.165
Subtract 3105 from 3640 to get 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Advancing to step 12:
621 can be fit into 5350 8 times, resulting in a remainder of 382.
The next digit of our result is 8. 
Result so far: 17237.1658
If we subtract 4968 from 5350, we get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

On to step 13:
When dividing 3820 by 621, we get 6 with a remainder of 94.
Use 6 as the next digit of our solution. 
Result so far: 17237.16586
If we take 3726 away from 3820, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 14:
If we divide 940 by 621, we get 1 and a remainder of 319.
The number 1 becomes the next digit in our result. 
Result so far: 17237.165861
If we take 621 away from 940, we end up with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Let's proceed to step 15:
The number 621 fits into 3190 5 times, leaving a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 17237.1658615
The remainder is 85 after subtracting 3105 from 3190.
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 16:
The number 621 fits into 850 1 times, leaving a remainder of 229.
Record the quotient 1 as the next digit in the result. 
Result so far: 17237.16586151
If we take 621 away from 850, we end up with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

After the division, we end up with 17237.16586151 and a remainder of 2.29e-07.
