Let's divide 49638121 by 747
We want to figure out the number of times 49638121 can be divided by 747.

Advancing to step 1:
If we divide 4 by 747, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 747

Advancing to step 2:
747 goes into 49 0 times with a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Grab the next digit (6) from the dividend, add it to 49, then carry on: 496 / 747

On to step 3:
The number 747 fits into 496 0 times, leaving a remainder of 496.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 496 after subtracting 0 from 496.
Take the next digit (3) from the dividend and append it to 496, then repeat: 4963 / 747

Moving on to step 4:
If we divide 4963 by 747, we get 6 and a remainder of 481.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 4482 from 4963 leaves us with 481.
Append the next digit (8) from the dividend to 481 and continue with: 4818 / 747

Moving on to step 5:
4818 divided by 747 is 6 with a remainder of 336.
The next digit of our result is 6. 
Result so far: 66.0
Subtract 4482 from 4818 to get 336.
Fetch the next digit (1) from the dividend, attach it to 336 and continue: 3361 / 747

Moving on to step 6:
747 can be fit into 3361 4 times, resulting in a remainder of 373.
Put 4 as the next digit of the answer. 
Result so far: 664.0
If we take 2988 away from 3361, we end up with 373.
Append the next digit (2) from the dividend to 373 and continue with: 3732 / 747

On to step 7:
When dividing 3732 by 747, we get 4 with a remainder of 744.
The number 4 becomes the next digit in our result. 
Result so far: 6644.0
Subtracting 2988 from 3732 leaves us with 744.
Grab the next digit (1) from the dividend, add it to 744, then carry on: 7441 / 747

Moving on to step 8:
If we divide 7441 by 747, we get 9 and a remainder of 718.
The number 9 becomes the next digit in our result. 
Result so far: 66449.0
Deduct 6723 from 7441 and we're left with 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

Step 9:
747 goes into 7180 9 times with a remainder of 457.
Use 9 as the next digit of our solution. 
Result so far: 66449.9
Deduct 6723 from 7180 and we're left with 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Moving on to step 10:
When dividing 4570 by 747, we get 6 with a remainder of 88.
Put 6 as the next digit of the answer. 
Result so far: 66449.96
Deduct 4482 from 4570 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 11:
747 can be fit into 880 1 times, resulting in a remainder of 133.
Use 1 as the next digit of our solution. 
Result so far: 66449.961
Deduct 747 from 880 and we're left with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Going ahead to step 12:
747 can be fit into 1330 1 times, resulting in a remainder of 583.
Put 1 as the next digit of the answer. 
Result so far: 66449.9611
Subtract 747 from 1330 to get 583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

Our division results in 66449.9611 with a remaining 0.00583.
