We divide 7989362 by 621
We want to figure out the number of times 7989362 can be divided by 621.

Let's proceed to step 1:
621 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 621

Moving on to step 2:
621 goes into 79 0 times with a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Grab the next digit (8) from the dividend, add it to 79, then carry on: 798 / 621

Going ahead to step 3:
The number 621 fits into 798 1 times, leaving a remainder of 177.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 621 from 798 leaves us with 177.
Fetch the next digit (9) from the dividend, attach it to 177 and continue: 1779 / 621

Going ahead to step 4:
If we divide 1779 by 621, we get 2 and a remainder of 537.
The next digit of our result is 2. 
Result so far: 12.0
If we take 1242 away from 1779, we end up with 537.
Grab the next digit (3) from the dividend, add it to 537, then carry on: 5373 / 621

Moving on to step 5:
When dividing 5373 by 621, we get 8 with a remainder of 405.
The number 8 becomes the next digit in our result. 
Result so far: 128.0
If we subtract 4968 from 5373, we get 405.
Take the next digit (6) from the dividend and append it to 405, then repeat: 4056 / 621

Going ahead to step 6:
621 goes into 4056 6 times with a remainder of 330.
Record the quotient 6 as the next digit in the result. 
Result so far: 1286.0
If we take 3726 away from 4056, we end up with 330.
Take the next digit (2) from the dividend and append it to 330, then repeat: 3302 / 621

Moving on to step 7:
The number 621 fits into 3302 5 times, leaving a remainder of 197.
Write down 5 as next digit of the result. 
Result so far: 12865.0
If we subtract 3105 from 3302, we get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Step 8:
1970 divided by 621 is 3 with a remainder of 107.
Use 3 as the next digit of our solution. 
Result so far: 12865.3
Subtract 1863 from 1970 to get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

On to step 9:
1070 divided by 621 is 1 with a remainder of 449.
Write down 1 as next digit of the result. 
Result so far: 12865.31
If we subtract 621 from 1070, we get 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

On to step 10:
If we divide 4490 by 621, we get 7 and a remainder of 143.
Put 7 as the next digit of the answer. 
Result so far: 12865.317
Subtracting 4347 from 4490 leaves us with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Advancing to step 11:
The number 621 fits into 1430 2 times, leaving a remainder of 188.
Record the quotient 2 as the next digit in the result. 
Result so far: 12865.3172
Subtracting 1242 from 1430 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 12:
621 can be fit into 1880 3 times, resulting in a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 12865.31723
If we subtract 1863 from 1880, we 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 13:
When dividing 170 by 621, we get 0 with a remainder of 170.
Write down 0 as next digit of the result. 
Result so far: 12865.31723
Subtract 0 from 170 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 14:
621 can be fit into 1700 2 times, resulting in a remainder of 458.
Write down 2 as next digit of the result. 
Result so far: 12865.3172302
The remainder is 458 after subtracting 1242 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

On to step 15:
621 can be fit into 4580 7 times, resulting in a remainder of 233.
The number 7 becomes the next digit in our result. 
Result so far: 12865.31723027
Subtract 4347 from 4580 to get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

The quotient of the division is 12865.31723027, and the remainder is 2.33e-07.
