91759685 divided by 420 
Let's see how many times 420 fits into 91759685.

On to step 1:
The number 420 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 420

On to step 2:
The number 420 fits into 91 0 times, leaving a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Grab the next digit (7) from the dividend, add it to 91, then carry on: 917 / 420

Step 3:
The number 420 fits into 917 2 times, leaving a remainder of 77.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 77 after subtracting 840 from 917.
Fetch the next digit (5) from the dividend, attach it to 77 and continue: 775 / 420

Step 4:
The number 420 fits into 775 1 times, leaving a remainder of 355.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we subtract 420 from 775, we get 355.
Take the next digit (9) from the dividend and append it to 355, then repeat: 3559 / 420

Moving on to step 5:
420 can be fit into 3559 8 times, resulting in a remainder of 199.
Use 8 as the next digit of our solution. 
Result so far: 218.0
The remainder is 199 after subtracting 3360 from 3559.
Fetch the next digit (6) from the dividend, attach it to 199 and continue: 1996 / 420

Step 6:
420 goes into 1996 4 times with a remainder of 316.
Write down 4 as next digit of the result. 
Result so far: 2184.0
Subtract 1680 from 1996 to get 316.
Grab the next digit (8) from the dividend, add it to 316, then carry on: 3168 / 420

Going ahead to step 7:
When dividing 3168 by 420, we get 7 with a remainder of 228.
Write down 7 as next digit of the result. 
Result so far: 21847.0
Subtracting 2940 from 3168 leaves us with 228.
Include the next digit (5) from the dividend after 228, then repeat: 2285 / 420

Advancing to step 8:
If we divide 2285 by 420, we get 5 and a remainder of 185.
Use 5 as the next digit of our solution. 
Result so far: 218475.0
The remainder is 185 after subtracting 2100 from 2285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Let's proceed to step 9:
When dividing 1850 by 420, we get 4 with a remainder of 170.
Put 4 as the next digit of the answer. 
Result so far: 218475.4
The remainder is 170 after subtracting 1680 from 1850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 10:
420 goes into 1700 4 times with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 218475.44
If we take 1680 away from 1700, we end up 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.

The final outcome is 218475.44, with a leftover of 0.02.
