Let's divide 986421 by 53
We want to divide 986421 by 53.

On to step 1:
53 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 53

On to step 2:
When dividing 98 by 53, we get 1 with a remainder of 45.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 45 after subtracting 53 from 98.
Bring next digit (6) of the dividend behind the 45 and repeat the process: 456 / 53

Moving on to step 3:
53 can be fit into 456 8 times, resulting in a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we take 424 away from 456, we end up with 32.
Append the next digit (4) from the dividend to 32 and continue with: 324 / 53

Let's proceed to step 4:
53 goes into 324 6 times with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 186.0
If we take 318 away from 324, we end up with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 53

Step 5:
53 can be fit into 62 1 times, resulting in a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1861.0
If we subtract 53 from 62, we get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 53

Step 6:
When dividing 91 by 53, we get 1 with a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 18611.0
If we subtract 53 from 91, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 7:
380 divided by 53 is 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 18611.7
If we take 371 away from 380, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 8:
53 can be fit into 90 1 times, resulting in a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 18611.71
Subtracting 53 from 90 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 9:
53 can be fit into 370 6 times, resulting in a remainder of 52.
The next digit of our result is 6. 
Result so far: 18611.716
If we take 318 away from 370, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 10:
53 can be fit into 520 9 times, resulting in a remainder of 43.
The next digit of our result is 9. 
Result so far: 18611.7169
Subtract 477 from 520 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 11:
The number 53 fits into 430 8 times, leaving a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 18611.71698
The remainder is 6 after subtracting 424 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 12:
53 goes into 60 1 times with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 18611.716981
If we subtract 53 from 60, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 13:
53 can be fit into 70 1 times, resulting in a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 18611.7169811
If we take 53 away from 70, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The quotient of the division is 18611.7169811, and the remainder is 1.7e-07.
