643156 divided by 37 
We're looking to find how many times 37 goes into 643156.

Going ahead to step 1:
37 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 37

Moving on to step 2:
When dividing 64 by 37, we get 1 with a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 37 away from 64, we end up with 27.
Bring next digit (3) of the dividend behind the 27 and repeat the process: 273 / 37

Advancing to step 3:
When dividing 273 by 37, we get 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 17.0
Subtracting 259 from 273 leaves us with 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 37

Moving on to step 4:
If we divide 141 by 37, we get 3 and a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 173.0
Subtract 111 from 141 to get 30.
Append the next digit (5) from the dividend to 30 and continue with: 305 / 37

Going ahead to step 5:
37 can be fit into 305 8 times, resulting in a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 1738.0
If we take 296 away from 305, we end up with 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 37

Let's proceed to step 6:
37 goes into 96 2 times with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 17382.0
Subtract 74 from 96 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
37 can be fit into 220 5 times, resulting in a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 17382.5
The remainder is 35 after subtracting 185 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 8:
350 divided by 37 is 9 with a remainder of 17.
The next digit of our result is 9. 
Result so far: 17382.59
If we take 333 away from 350, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
When dividing 170 by 37, we get 4 with a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 17382.594
Deduct 148 from 170 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 10:
The number 37 fits into 220 5 times, leaving a remainder of 35.
The next digit of our result is 5. 
Result so far: 17382.5945
If we take 185 away from 220, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 11:
37 goes into 350 9 times with a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 17382.59459
Subtract 333 from 350 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 12:
37 can be fit into 170 4 times, resulting in a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 17382.594594
If we take 148 away from 170, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 13:
37 can be fit into 220 5 times, resulting in a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 17382.5945945
Subtract 185 from 220 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 14:
37 goes into 350 9 times with a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 17382.59459459
Subtracting 333 from 350 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

In conclusion, the division gives 17382.59459459 with a balance of 1.7e-08.
