85403934 divided by 426 
Our goal is to divide 85403934 by 426.

Moving on to step 1:
When dividing 8 by 426, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 426

Moving on to step 2:
426 goes into 85 0 times with a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Bring next digit (4) of the dividend behind the 85 and repeat the process: 854 / 426

Step 3:
426 goes into 854 2 times with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 852 from 854 leaves us with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 426

Step 4:
426 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtract 0 from 20 to get 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 426

Let's proceed to step 5:
426 can be fit into 203 0 times, resulting in a remainder of 203.
Record the quotient 0 as the next digit in the result. 
Result so far: 200.0
Deduct 0 from 203 and we're left with 203.
Bring next digit (9) of the dividend behind the 203 and repeat the process: 2039 / 426

Moving on to step 6:
426 goes into 2039 4 times with a remainder of 335.
Record the quotient 4 as the next digit in the result. 
Result so far: 2004.0
Subtract 1704 from 2039 to get 335.
Bring next digit (3) of the dividend behind the 335 and repeat the process: 3353 / 426

Advancing to step 7:
The number 426 fits into 3353 7 times, leaving a remainder of 371.
Put 7 as the next digit of the answer. 
Result so far: 20047.0
Subtract 2982 from 3353 to get 371.
Take the next digit (4) from the dividend and append it to 371, then repeat: 3714 / 426

Advancing to step 8:
426 goes into 3714 8 times with a remainder of 306.
Record the quotient 8 as the next digit in the result. 
Result so far: 200478.0
Subtracting 3408 from 3714 leaves us with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Going ahead to step 9:
The number 426 fits into 3060 7 times, leaving a remainder of 78.
Record the quotient 7 as the next digit in the result. 
Result so far: 200478.7
If we subtract 2982 from 3060, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 10:
The number 426 fits into 780 1 times, leaving a remainder of 354.
Use 1 as the next digit of our solution. 
Result so far: 200478.71
Subtracting 426 from 780 leaves us with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Let's proceed to step 11:
3540 divided by 426 is 8 with a remainder of 132.
Record the quotient 8 as the next digit in the result. 
Result so far: 200478.718
The remainder is 132 after subtracting 3408 from 3540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 12:
If we divide 1320 by 426, we get 3 and a remainder of 42.
The next digit of our result is 3. 
Result so far: 200478.7183
Deduct 1278 from 1320 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 13:
420 divided by 426 is 0 with a remainder of 420.
Record the quotient 0 as the next digit in the result. 
Result so far: 200478.7183
Subtract 0 from 420 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 14:
When dividing 4200 by 426, we get 9 with a remainder of 366.
Put 9 as the next digit of the answer. 
Result so far: 200478.718309
Subtract 3834 from 4200 to get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Step 15:
426 can be fit into 3660 8 times, resulting in a remainder of 252.
Write down 8 as next digit of the result. 
Result so far: 200478.7183098
Subtract 3408 from 3660 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Going ahead to step 16:
If we divide 2520 by 426, we get 5 and a remainder of 390.
The next digit of our result is 5. 
Result so far: 200478.71830985
Subtract 2130 from 2520 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

The final outcome is 200478.71830985, with a leftover of 3.9e-07.
