Let's divide 7057997 by 421
We want to figure out the number of times 7057997 can be divided by 421.

On to step 1:
421 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 421

Step 2:
If we divide 70 by 421, we get 0 and a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Append the next digit (5) from the dividend to 70 and continue with: 705 / 421

On to step 3:
When dividing 705 by 421, we get 1 with a remainder of 284.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 421 from 705, we get 284.
Include the next digit (7) from the dividend after 284, then repeat: 2847 / 421

Advancing to step 4:
2847 divided by 421 is 6 with a remainder of 321.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 321 after subtracting 2526 from 2847.
Append the next digit (9) from the dividend to 321 and continue with: 3219 / 421

Step 5:
3219 divided by 421 is 7 with a remainder of 272.
Put 7 as the next digit of the answer. 
Result so far: 167.0
Subtracting 2947 from 3219 leaves us with 272.
Append the next digit (9) from the dividend to 272 and continue with: 2729 / 421

Advancing to step 6:
421 can be fit into 2729 6 times, resulting in a remainder of 203.
Record the quotient 6 as the next digit in the result. 
Result so far: 1676.0
The remainder is 203 after subtracting 2526 from 2729.
Grab the next digit (7) from the dividend, add it to 203, then carry on: 2037 / 421

Advancing to step 7:
If we divide 2037 by 421, we get 4 and a remainder of 353.
The next digit of our result is 4. 
Result so far: 16764.0
Deduct 1684 from 2037 and we're left with 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Step 8:
421 can be fit into 3530 8 times, resulting in a remainder of 162.
Write down 8 as next digit of the result. 
Result so far: 16764.8
Subtracting 3368 from 3530 leaves us with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Let's proceed to step 9:
When dividing 1620 by 421, we get 3 with a remainder of 357.
The number 3 becomes the next digit in our result. 
Result so far: 16764.83
The remainder is 357 after subtracting 1263 from 1620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Going ahead to step 10:
421 goes into 3570 8 times with a remainder of 202.
Use 8 as the next digit of our solution. 
Result so far: 16764.838
Subtract 3368 from 3570 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Going ahead to step 11:
When dividing 2020 by 421, we get 4 with a remainder of 336.
The next digit of our result is 4. 
Result so far: 16764.8384
Deduct 1684 from 2020 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 12:
If we divide 3360 by 421, we get 7 and a remainder of 413.
The number 7 becomes the next digit in our result. 
Result so far: 16764.83847
If we subtract 2947 from 3360, we get 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Advancing to step 13:
421 can be fit into 4130 9 times, resulting in a remainder of 341.
Use 9 as the next digit of our solution. 
Result so far: 16764.838479
The remainder is 341 after subtracting 3789 from 4130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Advancing to step 14:
When dividing 3410 by 421, we get 8 with a remainder of 42.
The next digit of our result is 8. 
Result so far: 16764.8384798
If we take 3368 away from 3410, 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 15:
The number 421 fits into 420 0 times, leaving a remainder of 420.
Put 0 as the next digit of the answer. 
Result so far: 16764.8384798
Subtract 0 from 420 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

After the division, we end up with 16764.8384798 and a remainder of 4.2e-07.
