66343424 ÷ 554 
We want to figure out the number of times 66343424 can be divided by 554.

Let's proceed to step 1:
6 divided by 554 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 554

Moving on to step 2:
The number 554 fits into 66 0 times, leaving a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Include the next digit (3) from the dividend after 66, then repeat: 663 / 554

On to step 3:
663 divided by 554 is 1 with a remainder of 109.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 109 after subtracting 554 from 663.
Grab the next digit (4) from the dividend, add it to 109, then carry on: 1094 / 554

Advancing to step 4:
554 goes into 1094 1 times with a remainder of 540.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 554 from 1094 and we're left with 540.
Bring next digit (3) of the dividend behind the 540 and repeat the process: 5403 / 554

Moving on to step 5:
554 can be fit into 5403 9 times, resulting in a remainder of 417.
Use 9 as the next digit of our solution. 
Result so far: 119.0
If we take 4986 away from 5403, we end up with 417.
Bring next digit (4) of the dividend behind the 417 and repeat the process: 4174 / 554

Step 6:
4174 divided by 554 is 7 with a remainder of 296.
Record the quotient 7 as the next digit in the result. 
Result so far: 1197.0
Subtracting 3878 from 4174 leaves us with 296.
Grab the next digit (2) from the dividend, add it to 296, then carry on: 2962 / 554

On to step 7:
If we divide 2962 by 554, we get 5 and a remainder of 192.
The next digit of our result is 5. 
Result so far: 11975.0
Subtracting 2770 from 2962 leaves us with 192.
Grab the next digit (4) from the dividend, add it to 192, then carry on: 1924 / 554

Let's proceed to step 8:
If we divide 1924 by 554, we get 3 and a remainder of 262.
Put 3 as the next digit of the answer. 
Result so far: 119753.0
Subtracting 1662 from 1924 leaves us with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

On to step 9:
When dividing 2620 by 554, we get 4 with a remainder of 404.
The number 4 becomes the next digit in our result. 
Result so far: 119753.4
Subtract 2216 from 2620 to get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Going ahead to step 10:
The number 554 fits into 4040 7 times, leaving a remainder of 162.
Use 7 as the next digit of our solution. 
Result so far: 119753.47
If we subtract 3878 from 4040, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

On to step 11:
If we divide 1620 by 554, we get 2 and a remainder of 512.
The number 2 becomes the next digit in our result. 
Result so far: 119753.472
If we subtract 1108 from 1620, we get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Advancing to step 12:
5120 divided by 554 is 9 with a remainder of 134.
The number 9 becomes the next digit in our result. 
Result so far: 119753.4729
Subtract 4986 from 5120 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Let's proceed to step 13:
When dividing 1340 by 554, we get 2 with a remainder of 232.
The number 2 becomes the next digit in our result. 
Result so far: 119753.47292
Subtract 1108 from 1340 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 14:
2320 divided by 554 is 4 with a remainder of 104.
Use 4 as the next digit of our solution. 
Result so far: 119753.472924
The remainder is 104 after subtracting 2216 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 15:
554 goes into 1040 1 times with a remainder of 486.
Use 1 as the next digit of our solution. 
Result so far: 119753.4729241
Deduct 554 from 1040 and we're left with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Going ahead to step 16:
When dividing 4860 by 554, we get 8 with a remainder of 428.
The next digit of our result is 8. 
Result so far: 119753.47292418
Deduct 4432 from 4860 and we're left with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

After the division, we end up with 119753.47292418 and a remainder of 4.28e-07.
