Let's divide 644351 by 97
We're looking to find how many times 97 goes into 644351.

On to step 1:
If we divide 6 by 97, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 97

Let's proceed to step 2:
97 goes into 64 0 times with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Fetch the next digit (4) from the dividend, attach it to 64 and continue: 644 / 97

Going ahead to step 3:
When dividing 644 by 97, we get 6 with a remainder of 62.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 582 from 644 to get 62.
Grab the next digit (3) from the dividend, add it to 62, then carry on: 623 / 97

On to step 4:
623 divided by 97 is 6 with a remainder of 41.
Put 6 as the next digit of the answer. 
Result so far: 66.0
The remainder is 41 after subtracting 582 from 623.
Bring next digit (5) of the dividend behind the 41 and repeat the process: 415 / 97

Going ahead to step 5:
When dividing 415 by 97, we get 4 with a remainder of 27.
Record the quotient 4 as the next digit in the result. 
Result so far: 664.0
If we take 388 away from 415, we end up with 27.
Grab the next digit (1) from the dividend, add it to 27, then carry on: 271 / 97

Let's proceed to step 6:
When dividing 271 by 97, we get 2 with a remainder of 77.
Put 2 as the next digit of the answer. 
Result so far: 6642.0
The remainder is 77 after subtracting 194 from 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 7:
97 goes into 770 7 times with a remainder of 91.
The next digit of our result is 7. 
Result so far: 6642.7
Subtracting 679 from 770 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Moving on to step 8:
When dividing 910 by 97, we get 9 with a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 6642.79
If we take 873 away from 910, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 9:
97 goes into 370 3 times with a remainder of 79.
Put 3 as the next digit of the answer. 
Result so far: 6642.793
Subtracting 291 from 370 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 10:
The number 97 fits into 790 8 times, leaving a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 6642.7938
Deduct 776 from 790 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 11:
140 divided by 97 is 1 with a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 6642.79381
Subtracting 97 from 140 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 12:
97 goes into 430 4 times with a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 6642.793814
If we take 388 away from 430, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 13:
97 goes into 420 4 times with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 6642.7938144
If we take 388 away from 420, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 6642.7938144 with a balance of 3.2e-07.
