We look at the division of 621943 by 37 
Let's see how many times 37 fits into 621943.

Advancing to step 1:
When dividing 6 by 37, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 37

On to step 2:
37 goes into 62 1 times with a remainder of 25.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 37 from 62 leaves us with 25.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 37

Step 3:
When dividing 251 by 37, we get 6 with a remainder of 29.
The next digit of our result is 6. 
Result so far: 16.0
Deduct 222 from 251 and we're left with 29.
Include the next digit (9) from the dividend after 29, then repeat: 299 / 37

Moving on to step 4:
37 can be fit into 299 8 times, resulting in a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 168.0
If we subtract 296 from 299, we get 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 37

Let's proceed to step 5:
37 can be fit into 34 0 times, resulting in a remainder of 34.
The next digit of our result is 0. 
Result so far: 1680.0
Deduct 0 from 34 and we're left with 34.
Take the next digit (3) from the dividend and append it to 34, then repeat: 343 / 37

Moving on to step 6:
The number 37 fits into 343 9 times, leaving a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 16809.0
The remainder is 10 after subtracting 333 from 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
The number 37 fits into 100 2 times, leaving a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 16809.2
If we take 74 away from 100, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 8:
260 divided by 37 is 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 16809.27
The remainder is 1 after subtracting 259 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
When dividing 10 by 37, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 16809.27
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
The number 37 fits into 100 2 times, leaving a remainder of 26.
The next digit of our result is 2. 
Result so far: 16809.2702
Subtracting 74 from 100 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 11:
260 divided by 37 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 16809.27027
The remainder is 1 after subtracting 259 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 12:
37 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 16809.27027
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 13:
The number 37 fits into 100 2 times, leaving a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 16809.2702702
If we subtract 74 from 100, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 14:
37 goes into 260 7 times with a remainder of 1.
The next digit of our result is 7. 
Result so far: 16809.27027027
If we subtract 259 from 260, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 16809.27027027 with a remainder of 1e-09.
