We're dividing 37455573 by 644 
Let's see how many times 644 fits into 37455573.

Going ahead to step 1:
If we divide 3 by 644, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 644

Moving on to step 2:
If we divide 37 by 644, we get 0 and a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Fetch the next digit (4) from the dividend, attach it to 37 and continue: 374 / 644

Step 3:
374 divided by 644 is 0 with a remainder of 374.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 374 after subtracting 0 from 374.
Include the next digit (5) from the dividend after 374, then repeat: 3745 / 644

Step 4:
3745 divided by 644 is 5 with a remainder of 525.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 3220 from 3745 leaves us with 525.
Grab the next digit (5) from the dividend, add it to 525, then carry on: 5255 / 644

On to step 5:
If we divide 5255 by 644, we get 8 and a remainder of 103.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
Deduct 5152 from 5255 and we're left with 103.
Bring next digit (5) of the dividend behind the 103 and repeat the process: 1035 / 644

Going ahead to step 6:
The number 644 fits into 1035 1 times, leaving a remainder of 391.
Put 1 as the next digit of the answer. 
Result so far: 581.0
Subtract 644 from 1035 to get 391.
Bring next digit (7) of the dividend behind the 391 and repeat the process: 3917 / 644

Going ahead to step 7:
The number 644 fits into 3917 6 times, leaving a remainder of 53.
Write down 6 as next digit of the result. 
Result so far: 5816.0
If we subtract 3864 from 3917, we get 53.
Fetch the next digit (3) from the dividend, attach it to 53 and continue: 533 / 644

Step 8:
When dividing 533 by 644, we get 0 with a remainder of 533.
Put 0 as the next digit of the answer. 
Result so far: 58160.0
The remainder is 533 after subtracting 0 from 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Moving on to step 9:
The number 644 fits into 5330 8 times, leaving a remainder of 178.
Put 8 as the next digit of the answer. 
Result so far: 58160.8
The remainder is 178 after subtracting 5152 from 5330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

On to step 10:
When dividing 1780 by 644, we get 2 with a remainder of 492.
Write down 2 as next digit of the result. 
Result so far: 58160.82
The remainder is 492 after subtracting 1288 from 1780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Going ahead to step 11:
644 goes into 4920 7 times with a remainder of 412.
Record the quotient 7 as the next digit in the result. 
Result so far: 58160.827
If we take 4508 away from 4920, we end up with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Moving on to step 12:
If we divide 4120 by 644, we get 6 and a remainder of 256.
Put 6 as the next digit of the answer. 
Result so far: 58160.8276
If we take 3864 away from 4120, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 13:
When dividing 2560 by 644, we get 3 with a remainder of 628.
Use 3 as the next digit of our solution. 
Result so far: 58160.82763
Subtract 1932 from 2560 to get 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Advancing to step 14:
If we divide 6280 by 644, we get 9 and a remainder of 484.
Write down 9 as next digit of the result. 
Result so far: 58160.827639
Subtracting 5796 from 6280 leaves us with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Advancing to step 15:
644 goes into 4840 7 times with a remainder of 332.
Write down 7 as next digit of the result. 
Result so far: 58160.8276397
If we take 4508 away from 4840, we end up with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 16:
644 goes into 3320 5 times with a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 58160.82763975
If we take 3220 away from 3320, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The quotient of the division is 58160.82763975, and the remainder is 1e-07.
