We're dividing 7644157 by 907 
Our goal is to divide 7644157 by 907.

On to step 1:
907 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 907

On to step 2:
The number 907 fits into 76 0 times, leaving a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 76, we end up with 76.
Bring next digit (4) of the dividend behind the 76 and repeat the process: 764 / 907

Going ahead to step 3:
764 divided by 907 is 0 with a remainder of 764.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 764 to get 764.
Fetch the next digit (4) from the dividend, attach it to 764 and continue: 7644 / 907

Advancing to step 4:
The number 907 fits into 7644 8 times, leaving a remainder of 388.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 7256 away from 7644, we end up with 388.
Fetch the next digit (1) from the dividend, attach it to 388 and continue: 3881 / 907

Moving on to step 5:
3881 divided by 907 is 4 with a remainder of 253.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
If we take 3628 away from 3881, we end up with 253.
Append the next digit (5) from the dividend to 253 and continue with: 2535 / 907

Going ahead to step 6:
The number 907 fits into 2535 2 times, leaving a remainder of 721.
The next digit of our result is 2. 
Result so far: 842.0
Subtracting 1814 from 2535 leaves us with 721.
Grab the next digit (7) from the dividend, add it to 721, then carry on: 7217 / 907

On to step 7:
7217 divided by 907 is 7 with a remainder of 868.
Write down 7 as next digit of the result. 
Result so far: 8427.0
Subtract 6349 from 7217 to get 868.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8680, and continue the process.

On to step 8:
If we divide 8680 by 907, we get 9 and a remainder of 517.
Use 9 as the next digit of our solution. 
Result so far: 8427.9
Subtracting 8163 from 8680 leaves us with 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

Moving on to step 9:
5170 divided by 907 is 5 with a remainder of 635.
The next digit of our result is 5. 
Result so far: 8427.95
Deduct 4535 from 5170 and we're left with 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

On to step 10:
If we divide 6350 by 907, we get 7 and a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 8427.957
If we take 6349 away from 6350, we end up with 1.
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 11:
When dividing 10 by 907, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 8427.957
Subtract 0 from 10 to 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.

Moving on to step 12:
If we divide 100 by 907, we get 0 and a remainder of 100.
The next digit of our result is 0. 
Result so far: 8427.957
Deduct 0 from 100 and we're left 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 8427.957, and the remainder is 0.0001.
