We look at the division of 7377998 by 646 
We want to figure out the number of times 7377998 can be divided by 646.

Moving on to step 1:
If we divide 7 by 646, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 646

Going ahead to step 2:
646 goes into 73 0 times with a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Include the next digit (7) from the dividend after 73, then repeat: 737 / 646

Advancing to step 3:
737 divided by 646 is 1 with a remainder of 91.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 646 away from 737, we end up with 91.
Append the next digit (7) from the dividend to 91 and continue with: 917 / 646

Advancing to step 4:
917 divided by 646 is 1 with a remainder of 271.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 646 from 917, we get 271.
Bring next digit (9) of the dividend behind the 271 and repeat the process: 2719 / 646

Step 5:
646 goes into 2719 4 times with a remainder of 135.
Put 4 as the next digit of the answer. 
Result so far: 114.0
The remainder is 135 after subtracting 2584 from 2719.
Bring next digit (9) of the dividend behind the 135 and repeat the process: 1359 / 646

Advancing to step 6:
1359 divided by 646 is 2 with a remainder of 67.
Record the quotient 2 as the next digit in the result. 
Result so far: 1142.0
If we subtract 1292 from 1359, we get 67.
Bring next digit (8) of the dividend behind the 67 and repeat the process: 678 / 646

Going ahead to step 7:
646 can be fit into 678 1 times, resulting in a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 11421.0
Subtract 646 from 678 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 8:
When dividing 320 by 646, we get 0 with a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 11421.0
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 9:
The number 646 fits into 3200 4 times, leaving a remainder of 616.
The number 4 becomes the next digit in our result. 
Result so far: 11421.04
Subtracting 2584 from 3200 leaves us with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

On to step 10:
If we divide 6160 by 646, we get 9 and a remainder of 346.
Use 9 as the next digit of our solution. 
Result so far: 11421.049
Subtract 5814 from 6160 to get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Moving on to step 11:
3460 divided by 646 is 5 with a remainder of 230.
The next digit of our result is 5. 
Result so far: 11421.0495
Subtracting 3230 from 3460 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 12:
646 goes into 2300 3 times with a remainder of 362.
The number 3 becomes the next digit in our result. 
Result so far: 11421.04953
Subtracting 1938 from 2300 leaves us with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Step 13:
3620 divided by 646 is 5 with a remainder of 390.
Put 5 as the next digit of the answer. 
Result so far: 11421.049535
Subtract 3230 from 3620 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 14:
The number 646 fits into 3900 6 times, leaving a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 11421.0495356
If we take 3876 away from 3900, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 15:
If we divide 240 by 646, we get 0 and a remainder of 240.
Put 0 as the next digit of the answer. 
Result so far: 11421.0495356
Subtracting 0 from 240 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final result is 11421.0495356 with a remainder of 2.4e-07.
