59405649 ÷ 420 
Let's see how many times 420 fits into 59405649.

Going ahead to step 1:
The number 420 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 420

Let's proceed to step 2:
420 can be fit into 59 0 times, resulting in a remainder of 59.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 59 and we're left with 59.
Include the next digit (4) from the dividend after 59, then repeat: 594 / 420

Going ahead to step 3:
The number 420 fits into 594 1 times, leaving a remainder of 174.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 420 from 594, we get 174.
Bring next digit (0) of the dividend behind the 174 and repeat the process: 1740 / 420

Advancing to step 4:
1740 divided by 420 is 4 with a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Deduct 1680 from 1740 and we're left with 60.
Grab the next digit (5) from the dividend, add it to 60, then carry on: 605 / 420

Step 5:
The number 420 fits into 605 1 times, leaving a remainder of 185.
The next digit of our result is 1. 
Result so far: 141.0
Deduct 420 from 605 and we're left with 185.
Take the next digit (6) from the dividend and append it to 185, then repeat: 1856 / 420

On to step 6:
If we divide 1856 by 420, we get 4 and a remainder of 176.
Record the quotient 4 as the next digit in the result. 
Result so far: 1414.0
Subtract 1680 from 1856 to get 176.
Grab the next digit (4) from the dividend, add it to 176, then carry on: 1764 / 420

Going ahead to step 7:
If we divide 1764 by 420, we get 4 and a remainder of 84.
The next digit of our result is 4. 
Result so far: 14144.0
If we take 1680 away from 1764, we end up with 84.
Bring next digit (9) of the dividend behind the 84 and repeat the process: 849 / 420

Let's proceed to step 8:
The number 420 fits into 849 2 times, leaving a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 141442.0
If we subtract 840 from 849, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
420 can be fit into 90 0 times, resulting in a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 141442.0
Subtract 0 from 90 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 10:
The number 420 fits into 900 2 times, leaving a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 141442.02
Deduct 840 from 900 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 11:
600 divided by 420 is 1 with a remainder of 180.
Put 1 as the next digit of the answer. 
Result so far: 141442.021
The remainder is 180 after subtracting 420 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 12:
420 goes into 1800 4 times with a remainder of 120.
Use 4 as the next digit of our solution. 
Result so far: 141442.0214
Subtract 1680 from 1800 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 13:
1200 divided by 420 is 2 with a remainder of 360.
Write down 2 as next digit of the result. 
Result so far: 141442.02142
Deduct 840 from 1200 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 14:
When dividing 3600 by 420, we get 8 with a remainder of 240.
Put 8 as the next digit of the answer. 
Result so far: 141442.021428
Deduct 3360 from 3600 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 15:
When dividing 2400 by 420, we get 5 with a remainder of 300.
Put 5 as the next digit of the answer. 
Result so far: 141442.0214285
If we subtract 2100 from 2400, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 16:
420 goes into 3000 7 times with a remainder of 60.
Write down 7 as next digit of the result. 
Result so far: 141442.02142857
The remainder is 60 after subtracting 2940 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 141442.02142857 and a remainder of 6e-08.
