68307553 ÷ 420 
We're looking to find how many times 420 goes into 68307553.

Moving on to step 1:
If we divide 6 by 420, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 420

Step 2:
420 goes into 68 0 times with a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Fetch the next digit (3) from the dividend, attach it to 68 and continue: 683 / 420

Advancing to step 3:
420 goes into 683 1 times with a remainder of 263.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 420 from 683 and we're left with 263.
Take the next digit (0) from the dividend and append it to 263, then repeat: 2630 / 420

Let's proceed to step 4:
When dividing 2630 by 420, we get 6 with a remainder of 110.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtract 2520 from 2630 to get 110.
Include the next digit (7) from the dividend after 110, then repeat: 1107 / 420

On to step 5:
When dividing 1107 by 420, we get 2 with a remainder of 267.
Record the quotient 2 as the next digit in the result. 
Result so far: 162.0
Subtracting 840 from 1107 leaves us with 267.
Include the next digit (5) from the dividend after 267, then repeat: 2675 / 420

Going ahead to step 6:
The number 420 fits into 2675 6 times, leaving a remainder of 155.
The next digit of our result is 6. 
Result so far: 1626.0
If we take 2520 away from 2675, we end up with 155.
Fetch the next digit (5) from the dividend, attach it to 155 and continue: 1555 / 420

On to step 7:
420 can be fit into 1555 3 times, resulting in a remainder of 295.
The next digit of our result is 3. 
Result so far: 16263.0
If we subtract 1260 from 1555, we get 295.
Grab the next digit (3) from the dividend, add it to 295, then carry on: 2953 / 420

Advancing to step 8:
420 goes into 2953 7 times with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 162637.0
Subtract 2940 from 2953 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 9:
420 goes into 130 0 times with a remainder of 130.
Use 0 as the next digit of our solution. 
Result so far: 162637.0
Subtract 0 from 130 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 10:
420 goes into 1300 3 times with a remainder of 40.
The next digit of our result is 3. 
Result so far: 162637.03
Deduct 1260 from 1300 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
420 can be fit into 400 0 times, resulting in a remainder of 400.
The next digit of our result is 0. 
Result so far: 162637.03
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 12:
If we divide 4000 by 420, we get 9 and a remainder of 220.
Write down 9 as next digit of the result. 
Result so far: 162637.0309
Deduct 3780 from 4000 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 13:
The number 420 fits into 2200 5 times, leaving a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 162637.03095
If we subtract 2100 from 2200, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 14:
The number 420 fits into 1000 2 times, leaving a remainder of 160.
Record the quotient 2 as the next digit in the result. 
Result so far: 162637.030952
Deduct 840 from 1000 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 15:
420 can be fit into 1600 3 times, resulting in a remainder of 340.
Use 3 as the next digit of our solution. 
Result so far: 162637.0309523
The remainder is 340 after subtracting 1260 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 16:
The number 420 fits into 3400 8 times, leaving a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 162637.03095238
Deduct 3360 from 3400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 162637.03095238 with a remaining 4e-08.
