50069591 ÷ 400 
We want to figure out the number of times 50069591 can be divided by 400.

Moving on to step 1:
5 divided by 400 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 400

Advancing to step 2:
When dividing 50 by 400, we get 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 50 leaves us with 50.
Fetch the next digit (0) from the dividend, attach it to 50 and continue: 500 / 400

Advancing to step 3:
If we divide 500 by 400, we get 1 and a remainder of 100.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 400 from 500 to get 100.
Bring next digit (6) of the dividend behind the 100 and repeat the process: 1006 / 400

Moving on to step 4:
The number 400 fits into 1006 2 times, leaving a remainder of 206.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 800 from 1006 to get 206.
Take the next digit (9) from the dividend and append it to 206, then repeat: 2069 / 400

Let's proceed to step 5:
2069 divided by 400 is 5 with a remainder of 69.
Use 5 as the next digit of our solution. 
Result so far: 125.0
The remainder is 69 after subtracting 2000 from 2069.
Fetch the next digit (5) from the dividend, attach it to 69 and continue: 695 / 400

Advancing to step 6:
400 goes into 695 1 times with a remainder of 295.
Record the quotient 1 as the next digit in the result. 
Result so far: 1251.0
If we take 400 away from 695, we end up with 295.
Bring next digit (9) of the dividend behind the 295 and repeat the process: 2959 / 400

Moving on to step 7:
The number 400 fits into 2959 7 times, leaving a remainder of 159.
Put 7 as the next digit of the answer. 
Result so far: 12517.0
Subtract 2800 from 2959 to get 159.
Bring next digit (1) of the dividend behind the 159 and repeat the process: 1591 / 400

Moving on to step 8:
The number 400 fits into 1591 3 times, leaving a remainder of 391.
Use 3 as the next digit of our solution. 
Result so far: 125173.0
The remainder is 391 after subtracting 1200 from 1591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Advancing to step 9:
400 goes into 3910 9 times with a remainder of 310.
Record the quotient 9 as the next digit in the result. 
Result so far: 125173.9
Subtract 3600 from 3910 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 10:
The number 400 fits into 3100 7 times, leaving a remainder of 300.
Put 7 as the next digit of the answer. 
Result so far: 125173.97
If we subtract 2800 from 3100, 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.

Advancing to step 11:
400 goes into 3000 7 times with a remainder of 200.
Record the quotient 7 as the next digit in the result. 
Result so far: 125173.977
Deduct 2800 from 3000 and we're left 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 quotient of the division is 125173.977, and the remainder is 0.02.
