We look at the division of 64637978 by 907 
Let's see how many times 907 fits into 64637978.

Step 1:
907 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.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 907

Let's proceed to step 2:
When dividing 64 by 907, we get 0 with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Fetch the next digit (6) from the dividend, attach it to 64 and continue: 646 / 907

Moving on to step 3:
If we divide 646 by 907, we get 0 and a remainder of 646.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 646 after subtracting 0 from 646.
Bring next digit (3) of the dividend behind the 646 and repeat the process: 6463 / 907

Moving on to step 4:
6463 divided by 907 is 7 with a remainder of 114.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 6349 away from 6463, we end up with 114.
Append the next digit (7) from the dividend to 114 and continue with: 1147 / 907

Let's proceed to step 5:
The number 907 fits into 1147 1 times, leaving a remainder of 240.
Use 1 as the next digit of our solution. 
Result so far: 71.0
Subtracting 907 from 1147 leaves us with 240.
Grab the next digit (9) from the dividend, add it to 240, then carry on: 2409 / 907

Moving on to step 6:
The number 907 fits into 2409 2 times, leaving a remainder of 595.
The next digit of our result is 2. 
Result so far: 712.0
Subtracting 1814 from 2409 leaves us with 595.
Fetch the next digit (7) from the dividend, attach it to 595 and continue: 5957 / 907

Step 7:
The number 907 fits into 5957 6 times, leaving a remainder of 515.
The next digit of our result is 6. 
Result so far: 7126.0
The remainder is 515 after subtracting 5442 from 5957.
Fetch the next digit (8) from the dividend, attach it to 515 and continue: 5158 / 907

Let's proceed to step 8:
If we divide 5158 by 907, we get 5 and a remainder of 623.
Use 5 as the next digit of our solution. 
Result so far: 71265.0
If we subtract 4535 from 5158, we get 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Advancing to step 9:
907 goes into 6230 6 times with a remainder of 788.
Use 6 as the next digit of our solution. 
Result so far: 71265.6
Subtracting 5442 from 6230 leaves us with 788.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7880, and continue the process.

Step 10:
907 goes into 7880 8 times with a remainder of 624.
Use 8 as the next digit of our solution. 
Result so far: 71265.68
The remainder is 624 after subtracting 7256 from 7880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

On to step 11:
6240 divided by 907 is 6 with a remainder of 798.
Record the quotient 6 as the next digit in the result. 
Result so far: 71265.686
If we take 5442 away from 6240, we end up with 798.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7980, and continue the process.

Moving on to step 12:
If we divide 7980 by 907, we get 8 and a remainder of 724.
Put 8 as the next digit of the answer. 
Result so far: 71265.6868
Deduct 7256 from 7980 and we're left with 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Advancing to step 13:
The number 907 fits into 7240 7 times, leaving a remainder of 891.
Record the quotient 7 as the next digit in the result. 
Result so far: 71265.68687
If we take 6349 away from 7240, we end up with 891.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8910, and continue the process.

Let's proceed to step 14:
If we divide 8910 by 907, we get 9 and a remainder of 747.
Put 9 as the next digit of the answer. 
Result so far: 71265.686879
Deduct 8163 from 8910 and we're left with 747.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7470, and continue the process.

On to step 15:
If we divide 7470 by 907, we get 8 and a remainder of 214.
The number 8 becomes the next digit in our result. 
Result so far: 71265.6868798
Subtract 7256 from 7470 to get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Step 16:
When dividing 2140 by 907, we get 2 with a remainder of 326.
Put 2 as the next digit of the answer. 
Result so far: 71265.68687982
Subtracting 1814 from 2140 leaves us with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

In conclusion, the division gives 71265.68687982 with a balance of 3.26e-07.
