We're dividing 49721 by 37 
We want to figure out the number of times 49721 can be divided by 37.

On to step 1:
4 divided by 37 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 37

On to step 2:
The number 37 fits into 49 1 times, leaving a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 12 after subtracting 37 from 49.
Append the next digit (7) from the dividend to 12 and continue with: 127 / 37

Moving on to step 3:
When dividing 127 by 37, we get 3 with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 111 away from 127, we end up with 16.
Grab the next digit (2) from the dividend, add it to 16, then carry on: 162 / 37

On to step 4:
When dividing 162 by 37, we get 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 134.0
If we take 148 away from 162, we end up with 14.
Include the next digit (1) from the dividend after 14, then repeat: 141 / 37

Going ahead to step 5:
The number 37 fits into 141 3 times, leaving a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 1343.0
Deduct 111 from 141 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 6:
300 divided by 37 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 1343.8
The remainder is 4 after subtracting 296 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
37 can be fit into 40 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1343.81
Deduct 37 from 40 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 8:
When dividing 30 by 37, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 1343.81
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
If we divide 300 by 37, we get 8 and a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 1343.8108
The remainder is 4 after subtracting 296 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
The number 37 fits into 40 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1343.81081
If we subtract 37 from 40, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 11:
The number 37 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 1343.81081
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
The number 37 fits into 300 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 1343.8108108
Subtract 296 from 300 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 13:
When dividing 40 by 37, we get 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1343.81081081
If we subtract 37 from 40, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 1343.81081081 with a remainder of 3e-09.
