69301568 ÷ 421 
We want to divide 69301568 by 421.

Let's proceed to step 1:
The number 421 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 421

Going ahead to step 2:
When dividing 69 by 421, we get 0 with a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Include the next digit (3) from the dividend after 69, then repeat: 693 / 421

Moving on to step 3:
421 can be fit into 693 1 times, resulting in a remainder of 272.
The next digit of our result is 1. 
Result so far: 1.0
If we take 421 away from 693, we end up with 272.
Take the next digit (0) from the dividend and append it to 272, then repeat: 2720 / 421

Step 4:
The number 421 fits into 2720 6 times, leaving a remainder of 194.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we take 2526 away from 2720, we end up with 194.
Bring next digit (1) of the dividend behind the 194 and repeat the process: 1941 / 421

Advancing to step 5:
The number 421 fits into 1941 4 times, leaving a remainder of 257.
Write down 4 as next digit of the result. 
Result so far: 164.0
Subtract 1684 from 1941 to get 257.
Append the next digit (5) from the dividend to 257 and continue with: 2575 / 421

Advancing to step 6:
421 goes into 2575 6 times with a remainder of 49.
Use 6 as the next digit of our solution. 
Result so far: 1646.0
Subtracting 2526 from 2575 leaves us with 49.
Fetch the next digit (6) from the dividend, attach it to 49 and continue: 496 / 421

Let's proceed to step 7:
When dividing 496 by 421, we get 1 with a remainder of 75.
Put 1 as the next digit of the answer. 
Result so far: 16461.0
The remainder is 75 after subtracting 421 from 496.
Include the next digit (8) from the dividend after 75, then repeat: 758 / 421

Advancing to step 8:
When dividing 758 by 421, we get 1 with a remainder of 337.
Write down 1 as next digit of the result. 
Result so far: 164611.0
Subtracting 421 from 758 leaves us with 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Moving on to step 9:
421 can be fit into 3370 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 164611.8
If we take 3368 away from 3370, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
20 divided by 421 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 164611.8
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
When dividing 200 by 421, we get 0 with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 164611.8
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 164611.8, with a leftover of 0.02.
