Let's divide 553621 by 69
We're looking to find how many times 69 goes into 553621.

Going ahead to step 1:
5 divided by 69 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 69

Advancing to step 2:
69 can be fit into 55 0 times, resulting in a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Append the next digit (3) from the dividend to 55 and continue with: 553 / 69

On to step 3:
69 can be fit into 553 8 times, resulting in a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 552 from 553, we get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 69

Advancing to step 4:
If we divide 16 by 69, we get 0 and a remainder of 16.
The next digit of our result is 0. 
Result so far: 80.0
If we subtract 0 from 16, we get 16.
Fetch the next digit (2) from the dividend, attach it to 16 and continue: 162 / 69

On to step 5:
69 goes into 162 2 times with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 802.0
The remainder is 24 after subtracting 138 from 162.
Append the next digit (1) from the dividend to 24 and continue with: 241 / 69

Advancing to step 6:
If we divide 241 by 69, we get 3 and a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 8023.0
Deduct 207 from 241 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 7:
When dividing 340 by 69, we get 4 with a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 8023.4
If we subtract 276 from 340, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 8:
The number 69 fits into 640 9 times, leaving a remainder of 19.
The next digit of our result is 9. 
Result so far: 8023.49
If we subtract 621 from 640, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 9:
190 divided by 69 is 2 with a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 8023.492
Subtracting 138 from 190 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 10:
520 divided by 69 is 7 with a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 8023.4927
If we take 483 away from 520, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 11:
If we divide 370 by 69, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 8023.49275
Subtract 345 from 370 to get 25.
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 12:
69 can be fit into 250 3 times, resulting in a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 8023.492753
The remainder is 43 after subtracting 207 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 13:
If we divide 430 by 69, we get 6 and a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 8023.4927536
If we subtract 414 from 430, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
The number 69 fits into 160 2 times, leaving a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 8023.49275362
If we subtract 138 from 160, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

After the division, we end up with 8023.49275362 and a remainder of 2.2e-08.
