54966308 ÷ 749 
We want to figure out the number of times 54966308 can be divided by 749.

Step 1:
749 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 749

Moving on to step 2:
749 goes into 54 0 times with a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Fetch the next digit (9) from the dividend, attach it to 54 and continue: 549 / 749

Moving on to step 3:
The number 749 fits into 549 0 times, leaving a remainder of 549.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 549 after subtracting 0 from 549.
Fetch the next digit (6) from the dividend, attach it to 549 and continue: 5496 / 749

Step 4:
If we divide 5496 by 749, we get 7 and a remainder of 253.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 5243 away from 5496, we end up with 253.
Append the next digit (6) from the dividend to 253 and continue with: 2536 / 749

Let's proceed to step 5:
749 can be fit into 2536 3 times, resulting in a remainder of 289.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
The remainder is 289 after subtracting 2247 from 2536.
Bring next digit (3) of the dividend behind the 289 and repeat the process: 2893 / 749

Advancing to step 6:
749 goes into 2893 3 times with a remainder of 646.
The next digit of our result is 3. 
Result so far: 733.0
Deduct 2247 from 2893 and we're left with 646.
Take the next digit (0) from the dividend and append it to 646, then repeat: 6460 / 749

Moving on to step 7:
If we divide 6460 by 749, we get 8 and a remainder of 468.
Put 8 as the next digit of the answer. 
Result so far: 7338.0
If we subtract 5992 from 6460, we get 468.
Fetch the next digit (8) from the dividend, attach it to 468 and continue: 4688 / 749

Step 8:
If we divide 4688 by 749, we get 6 and a remainder of 194.
Record the quotient 6 as the next digit in the result. 
Result so far: 73386.0
Subtract 4494 from 4688 to get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Let's proceed to step 9:
When dividing 1940 by 749, we get 2 with a remainder of 442.
The next digit of our result is 2. 
Result so far: 73386.2
Subtract 1498 from 1940 to get 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Moving on to step 10:
When dividing 4420 by 749, we get 5 with a remainder of 675.
Use 5 as the next digit of our solution. 
Result so far: 73386.25
If we take 3745 away from 4420, we end up with 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Advancing to step 11:
6750 divided by 749 is 9 with a remainder of 9.
The next digit of our result is 9. 
Result so far: 73386.259
Deduct 6741 from 6750 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 12:
749 can be fit into 90 0 times, resulting in a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 73386.259
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 13:
The number 749 fits into 900 1 times, leaving a remainder of 151.
The next digit of our result is 1. 
Result so far: 73386.25901
The remainder is 151 after subtracting 749 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

On to step 14:
749 can be fit into 1510 2 times, resulting in a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 73386.259012
If we take 1498 away from 1510, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 15:
The number 749 fits into 120 0 times, leaving a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 73386.259012
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 16:
When dividing 1200 by 749, we get 1 with a remainder of 451.
The next digit of our result is 1. 
Result so far: 73386.25901201
Deduct 749 from 1200 and we're left with 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

The final result is 73386.25901201 with a remainder of 4.51e-07.
